Compact car is a vehicle size class —predominantly used in North America—that sits between subcompact cars and mid-size cars . "Small family car" is a British term and a part of the C-segment in the European car classification. However, before the downsizing of the United States car industry in the 1970s and 1980s, larger vehicles with wheelbases up to 110 in (2.79 m) were considered "compact cars" in the United States.

104-782: The Toyota Matrix , officially named Toyota Corolla Matrix , is a compact hatchback manufactured by Toyota Motor Manufacturing Canada in Cambridge, Ontario and derived from the Corolla . Introduced in 2002 as a 2003 model, the Matrix was the result of a joint venture between Toyota and General Motors , with the GM version being the Pontiac Vibe , which was assembled by New United Motor Manufacturing, Inc. ( NUMMI ) in Fremont, California , United States. The Matrix

208-411: A 7075 alloy and hard anodised for a lasting finish. The outer disc ring is usually manufactured from grey iron . They can also be from steel or carbon ceramic for particular applications. These materials originated from motorsport use and are available in high-performance vehicles and aftermarket upgrades. Two-piece discs can be supplied as a fixed assembly with regular nuts, bolts, and washers or

312-412: A Subaru WRX wagon with 61.1 cu ft (1.73 m) of space. In addition to the eight tie-downs in the back for attaching the included cargo nets and tonneau cover , the seats and rear floor have integrated rails for installing extra tie-downs. Up front, the passenger seat also folds flat, accommodating long items like surf boards or allowing drivers to use the tray in its back to hold items like

416-410: A recall for 2003 and 2004 model year Corollas and Matrixes. The recall notice cites two bolts in each of the front doors as potentially causing the window to come off the track and break. This recall only applies to models equipped with power windows. General Motors issued a recall for the same problem on 2003 and 2004 Pontiac Vibes with power windows at the same time. On August 26, 2010, Toyota issued

520-451: A recall for 2005 to 2008 model year Corollas and Matrixes, equipped with the 1ZZ-FE engine and two-wheel drive. The recall notices states that an improperly manufactured Engine Control Module (ECM) can develop a crack in its circuitry, potentially causing the "Check Engine" light to illuminate, harsh shifting, and stalling and/or failure of the engine to start. On November 20, 2019, along with 2003-2008 Corollas and 2004 and 2005 Yarises ,

624-440: A servo-effect . By contrast, a disc brake has no self-servo effect, and its braking force is always proportional to the pressure placed on the brake pad by the braking system via any brake servo, brake pedal, or lever. This tends to give the driver a better "feel" and helps to avoid impending lockup. Drums are also prone to "bell mouthing" and trap worn lining material within the assembly, causing various braking problems. The disc

728-609: A "compact car" target that was larger than what has become known as the "light car" or the kei car . One of the first compact cars that met those requirements was the Toyota Publica with an air-cooled two-cylinder opposed engine, the Datsun 110 series , and the Mitsubishi 500 . The Publica and the Mitsubishi 500 were essentially "kei cars" with engines larger than regulations permitted at

832-592: A 1.8 L-powered base model, and the XR , XRS and AWD models with a 2.4-liter engine. This generation marks the first time the Matrix was sold in Mexico . The Matrix comes only in two trim levels to Mexico: Base and XR. For the 2011 model year, the Matrix received redesigned exterior and interior elements, including front and rear fascias, wheels and seat fabrics. The radio was also changed to allow for Bluetooth capability. In 2008, Toyota began offering different trim levels in

936-713: A 1956 TR3 with disc brakes to the public, but the first production cars with Girling front-disc brakes were made in September 1956. Jaguar began to offer disc brakes in February 1957 on the XK150 model, soon to follow with the Mark 1 sports saloon and in 1959 with the Mark IX large saloon. Disc brakes were most popular on sports cars when they were first introduced since these vehicles are more demanding about brake performance. Discs have now become

1040-477: A Crosley HotShot with stock four-wheel disc brakes won the Index of Performance in the first race at Sebring (six hours rather than 12) on New Year's Eve in 1950. The Citroën DS was the first sustained mass production use of modern automotive disc brakes, in 1955. The car featured caliper-type front disc brakes among its many innovations. These discs were mounted inboard near the transmission and were powered by

1144-402: A bike gets into a violent tank-slapper (high-speed oscillation of the front wheel) the brake pads in the calipers are forced away from the discs, so when the rider applies the brake lever, the caliper pistons push the pads towards the discs without actually making contact. The rider then brakes harder, forcing the pads onto the disc much more aggressively than standard braking. An example of this

1248-526: A fairly youthful market segment. This type of car is also commonly referred to as a sport wagon . First sold in February 2002, the Matrix saw a minor facelift for the 2005 model year , and was redesigned completely in 2008 for the 2009 model year, following the tenth generation Corolla . Sales of the Matrix were discontinued in the United States in 2013 and in Canada in 2014. The Matrix was first introduced in

1352-431: A fixed caliper. A floating disc also avoids disc warping and reduces heat transfer to the wheel hub. Calipers have evolved from simple single-piston units to two-, four- and even six-piston items. Compared to cars, motorcycles have a higher center of mass : wheelbase ratio, so they experience more weight transfer when braking. Front brakes absorb most of the braking forces, while the rear brake serves mainly to balance

1456-767: A fork brace, USD forks may be best stiffened by an oversized front axle). Bike disc brakes may range from simple, mechanical (cable) systems, to expensive and powerful, multi-piston hydraulic disc systems, commonly used on downhill racing bikes . Improved technology has seen the creation of vented discs for use on mountain bikes , similar to those on cars, introduced to help avoid heat fade on fast alpine descents. Discs are also used on road bicycles for all-weather cycling with predictable braking. By 2024, almost all road bikes are equipped with disc brakes, just like Mountain bikes. Drums are sometimes preferred as harder to damage in crowded parking, where discs are sometimes bent. Most bicycle brake discs are made of steel. Stainless steel

1560-440: A laptop computer. An electronic device can be charged with the 115 volt/100 watt power inverter (US models only). The first year of production (2003), the instrument cluster was completely red. However, the next year, Toyota made the numbers white while keeping the rest of the gauges red. When the car was updated in 2005, a digital clock was added to the radio bezel. NHTSA crash test ratings (2003): In May 2008, Toyota issued

1664-460: A leather-wrapped steering wheel, and a panic button on the key fob . Options available with the XR trim included a sunroof , body kit, and 17-inch (430 mm) alloy wheels . A 2003 XR started at US$ 16,180 and 2,701 lb (1,225 kg), but when equipped with AWD cost at least $ 18,445 (only $ 305 less than an XRS) and weighed in at 2,965 lb (1,345 kg). Like the base model, the XR's AWD engine

1768-512: A license plate number beginning with "5". In the past, the small size category has received tax benefits stipulated by the Japanese government regulations , such as those in the 1951 Road Vehicle Act . In 1955, the Japanese Ministry of International Trade and Industry set forth a goal to all Japanese makers at that time to create what was called a "national car". The concept stipulated that

1872-667: A more complicated floating system where drive bobbins allow the two parts of the brake disc to expand and contract at different rates, therefore, reducing the chance a disc will warp from overheating. Key advantages of a two-piece disc are a saving in critical un-sprung weight and the dissipation of heat from the disc surface through the alloy bell (hat). Both fixed and floating options have their drawbacks and advantages. Floating discs are prone to rattle and collection of debris and are best suited to motorsport, whereas fixed are best for road use. The development of disc brakes began in England in

1976-745: A new market segment and the U.S. automobile industry soon adopted the "compact" term. Several competitors to the Nash Rambler arose from the ranks of America's other independent automakers, although none enjoyed the long-term success of the Rambler. Other early compact cars included the Kaiser-Frazer Henry J (also re-badged as the Allstate ), the Willys Aero and the Hudson Jet . In 1954, 64,500 cars sold in

2080-430: A semi-independent torsion beam . The 2009 models have less interior space than the preceding years, with a total of 48.9 cu ft (1.38 m) compared to the original 53.2 cu ft (1.51 m). The XRS trim was dropped from the U.S. lineup for the 2011 model year. All models come standard with side torso airbags , side curtain airbags , anti-lock braking and electronic brakeforce distribution . For

2184-604: A single stop. For these reasons, a heavy truck with disc brakes can stop in about 120% of the distance of a passenger car, but with drums, stopping takes about 150% of the distance. In Europe, stopping distance regulations essentially require disc brakes for heavy vehicles. In the U.S., drums are allowed and are typically preferred for their lower purchase price, despite higher total lifetime cost and more frequent service intervals. Still-larger discs are used for railroad cars , trams , and some airplanes . Passenger rail cars and light rail vehicles often use disc brakes outboard of

2288-447: A six-speed manual transmission was the only gearbox offered in the XRS. A Transitional Low Emission Vehicle ( TLEV ) its first year of production, the 2ZZ was retrofitted in 2004 with a smog pump and reclassified as an Ultra Low Emission Vehicle (ULEV). The Matrix was able to come to a full stop from 60 mph (97 km/h) in only 114 feet (35 m). Due to being front wheel drive ,

2392-475: A specification for the manufacture of grey iron for various applications. For normal car and light-truck applications, SAE specification J431 G3000 (superseded to G10) dictates the correct range of hardness, chemical composition, tensile strength, and other properties necessary for the intended use. Some racing cars and airplanes use brakes with carbon fiber discs and carbon fiber pads to reduce weight. Wear rates tend to be high, and braking may be poor or grabby until

2496-412: A spoiler. To improve handling, a "sport tuned suspension" and strut tower brace were included. One of the Matrix's unique design features is its interior, particularly the rear 60/40 seats and cargo area. Made with rigid plastic backs, the rear seats fold flat, creating a 53.2 cu ft (1.51 m) cargo area. In a practicality test, Motor Trend was able to haul more cargo in the Matrix than in

2600-443: A sunroof. An option combining 17-inch (430 mm) wheels and a sunroof became available the second year of production. In 2005, an XRS started out at $ 18,850, and for its last year, it sold for at least $ 19,250. The XRS trim included an engine upgrade to Toyota's higher-performance 2ZZ-GE engine. Displacing 1,796 cc (1.796 L; 109.6 cu in), it produced 180 hp (134 kW) and 130 lb⋅ft (176 N⋅m) –

2704-421: A then-rare 100 horsepower-per-liter . While its 11.5:1 compression ratio was a large factor in its performance, the engine could change to a second cam profile at higher RPM through Toyota's VVTL-i and was designed for operation up to 8500 RPM. The engine's high compression necessitates "premium" gasoline (91 octane or above in the (R+M)/2 scale ). With the exception of an available automatic in 2003,

2808-467: Is converted into heat , which must be dissipated to the environment. Hydraulically actuated disc brakes are the most commonly used mechanical device for slowing motor vehicles. The principles of a disc brake apply to almost any rotating shaft. The components include the disc, master cylinder , and caliper, which contain at least one cylinder and two brake pads on both sides of the rotating disc. The development of disc-type brakes began in England in

2912-482: Is done mainly where the cost of a new disc may be lower than the cost of labor to resurface the old disc. Mechanically this is unnecessary unless the discs have reached the manufacturer's minimum recommended thickness, which would make it unsafe to use them, or vane rusting is severe (ventilated discs only). Most leading vehicle manufacturers recommend brake disc skimming (US: turning) as a solution for lateral run-out, vibration issues, and brake noises. The machining process

3016-439: Is performed in a brake lathe , which removes a very thin layer off the disc surface to clean off minor damage and restore uniform thickness. Machining the disc as necessary will maximize the mileage out of the current discs on the vehicle. Run-out is measured using a dial indicator on a fixed rigid base, with the tip perpendicular to the brake disc's face. It is typically measured about 1 ⁄ 2  in (12.7 mm) from

3120-414: Is preferred due to its anti-rust properties. Discs are thin, often about 2 mm. Some use a two-piece floating disc style, others use a one-piece solid metal disc. Bicycle disc brakes use either a two-piston caliper that clamps the disc from both sides or a single-piston caliper with one moving pad that contacts the disc first, and then pushes the disc against the non-moving pad. Because energy efficiency

3224-401: Is so important in bicycles, an uncommon feature of bicycle brakes is that the pads retract to eliminate residual drag when the brake is released. In contrast, most other brakes drag the pads lightly when released to minimize initial operational travel. Disc brakes are increasingly used on very large and heavy road vehicles, where previously large drum brakes were nearly universal. One reason

3328-430: Is that the disc's lack of self-assist makes brake force much more predictable, so peak brake force can be raised without more risk of braking-induced steering or jackknifing on articulated vehicles. Another is disc brakes fade less when hot, and in a heavy vehicle air and rolling drag and engine braking are small parts of total braking force, so brakes are used harder than on lighter vehicles, and drum brake fade can occur in

3432-399: Is usually made of cast iron . In some cases, it may be made of composites such as reinforced carbon–carbon or ceramic matrix composites . This is connected to the wheel and the axle . To slow down the wheel, friction material in the form of brake pads , mounted on the brake caliper , is forced mechanically, hydraulically , pneumatically , or electromagnetically against both sides of

3536-441: The 2009–2011 Toyota vehicle recalls regarding floor mat and accelerator pedal replacement. On October 10, 2012, Toyota issued a recall for 2009 model year Corolla and Matrix, along with 10 other models. The recall notices states that improperly lubricated driver's side power window master switch may develop a "notchy" or sticky feel, and that improper aftermarket lubrication may present a fire hazard. The repair involves lubricating

3640-587: The Arado Ar 96 . The German Tiger I heavy tank, was introduced in 1942 with a 55 cm Argus-Werke disc on each drive shaft. The American Crosley Hot Shot had four-wheel disc brakes in 1949 and 1950. However, these quickly proved troublesome and were removed. Crosley returned to drum brakes, and drum brake conversions for Hot Shots were popular. Lack of sufficient research caused reliability problems, such as sticking and corrosion, especially in regions using salt on winter roads. Crosley four-wheel disc brakes made

3744-567: The Daimler Company used disc brakes on its Daimler Armoured Car of 1939. The disc brakes, made by the Girling company, were necessary because in that four-wheel drive (4×4) vehicle the epicyclic final drive was in the wheel hubs and therefore left no room for conventional hub-mounted drum brakes . At Germany's Argus Motoren , Hermann Klaue (1912-2001) had patented disc brakes in 1940. Argus supplied wheels fitted with disc brakes e.g. for

3848-529: The Lincoln Continental . A four-wheel disc brake system was also introduced in 1965 on the Chevrolet Corvette Stingray. Most U.S. cars switched from front drum brakes to front disk brakes in the late 1970s and early 1980s. Lambretta introduced the first high-volume production use of a single, floating, front disc brake, enclosed in a ventilated cast alloy hub and actuated by cable, on

3952-681: The Recession of 1958 , the only exception to the sales decline was American Motors with its compact, economy-oriented Ramblers that saw high demand among cautious consumers. By 1959, sales of small imported cars also increased to 14% of the U.S. passenger car market, as consumers turned to compact cars. By this time, smaller cars appealed to people with a college education and a higher income whose families were buying more than one car. Customers expected compact cars to provide improved fuel economy compared to full-sized cars while maintaining headroom, legroom, and plenty of trunk space. Between 1958 and 1960,

4056-525: The Studebaker Avanti was factory-equipped with front disc brakes as standard equipment. This Bendix system licensed from Dunlop was also optional on some of the other Studebaker models. Front disc brakes became standard equipment on the 1965 Rambler Marlin . The Bendix units were optional on all American Motors ' Rambler Classic and Ambassador models as well as on the Ford Thunderbird , and

4160-452: The driveshaft , near the differential , while most brakes today are located inside the wheels. An inboard location reduces the unsprung weight and eliminates a source of heat transfer to the tires. Historically, brake discs were manufactured worldwide with a concentration in Europe and America. Between 1989 and 2005, the manufacturing of brake discs migrated predominantly to China. In 1963,

4264-466: The "small Ford" and produced the Ford Vedette . The first U.S.-produced postwar compact car was the 1950 Nash Rambler . It was built on a 100-inch (2,540 mm) wheelbase, which was nonetheless still a large car by contemporary European standards. The term "compact" was coined by a Nash executive as a euphemism for small cars with a wheelbase of 110 inches (2,794 mm) or less. It established

4368-472: The 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated similarly to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for another 60 years. Successful application began in airplanes before World War II. The German Tiger tank was fitted with discs in 1942. After

4472-415: The 1890s. The first caliper-type automobile disc brake was patented by Frederick William Lanchester in his Birmingham factory in 1902 and used successfully on Lanchester cars . However, the limited choice of metals in this period meant he used copper as the braking medium acting on the disc. The poor state of the roads at this time, no more than dusty, rough tracks, meant that the copper wore quickly, making

4576-547: The 1962 TV175. This was followed by the GT200 in 1964. MV Agusta was the second manufacturer to offer a front disc brake motorcycle to the public on a small scale in 1965, on their expensive 600 touring motorcycle featuring cable-operated mechanical actuation. In 1969, Honda introduced the more affordable CB750 , which had a single hydraulically actuated front disc brake (and a rear drum brake), and which sold in huge numbers. Unlike cars, disc brakes that are located within

4680-791: The 1980s that American cars were being downsized to truly international dimensions. In the 1985 model year, compact cars classified by the EPA included Ford's Escort and Tempo as well as the Chevrolet Cavalier. For the 2019 model year, the best sellers were the Toyota Corolla and Honda Civic. In Japan, vehicles that are larger than kei cars , but with dimensions smaller than 4,700 mm (185.0 in) long, 1,700 mm (66.9 in) wide, 2,000 mm (78.7 in) high and with engines at or under 2,000 cc (120 cu in) are classified as "small size" cars. Small-size cars are identified by

4784-415: The 1ZZ engine and automatic transmission, but was dropped at the same time as the XRS. Starting out at US$ 14,670 in 2003, the no-frills base model came with few options. While it did have standard air conditioning, it left out features like color-keyed mirrors and door handles, blacked out window frames and power mirrors. One option the base model could be had with was AWD for an additional $ 1,465 (although

4888-431: The 2003 model year and based on the Toyota Corolla platform. Relatively unchanged in 2004, a facelift for 2005 brought minor revisions to the exterior – mainly revised styling to the front fascia due to complaints of rubbing the ground on the previous incarnation and replacing the red lenses on the taillamps with clear ones. Also, the center instrument panel was slightly redesigned and featured a Toyota head unit in place of

4992-424: The 2010 model the previously optional Vehicle Stability Control and traction control systems became standard. Toyota's Smart Stop Technology was added to the Matrix for the 2011 model year. The Matrix is rated "Good" in both frontal and side Insurance Institute for Highway Safety (IIHS) crash tests. NHTSA crash test ratings (2009): The 2009 to 2010 model year Matrix (and its Vibe relative) are subject to

5096-532: The French Venturi sports car manufacturer in the mid-1990s for example, but need to reach a very high operating temperature before becoming truly effective and so are not well suited to road use. The extreme heat generated in these systems is visible during night racing, especially on shorter tracks. It is not uncommon to see the brake discs glowing red during use. Ceramic discs are used in some high-performance cars and heavy vehicles. The first development of

5200-613: The Honda City, Toyota Yaris, Toyota Corolla Altis 1.6, and the Changan Alsvin. Disc brakes A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a rotor to create friction . There are two basic types of brake pad friction mechanisms: abrasive friction and adherent friction. This action slows the rotation of a shaft, such as a vehicle axle , either to reduce its rotational speed or to hold it stationary. The energy of motion

5304-495: The Matrix of the model years from 2003 to 2008 was recalled in Mexico due to these cars containing Takata frontal passenger airbags which might degrade due to weather exposure and variation of high temperatures, which usually occurs on cities with extreme weather, which might cause serious injuries on passengers. Toyota has advised all owners of the following cars to replace these faulty frontal passenger airbags or all airbags, depending on

5408-407: The U.S. were imports or small American cars, out of a total market of five million cars. Market research indicated that five percent of those surveyed said they would consider a small car, suggesting a potential market size of 275,000 cars. By 1955, the Nash Rambler that began as a convertible model became a success and was now available in station wagon , hardtop , and sedan body styles. During

5512-401: The United States and Canada. The XR trim became exclusive for Canada, and the S trim was released only in the U.S., while AWD remained available in both markets after 2009. All vehicles have an independent front suspension with MacPherson struts , but only XRS trim and cars equipped with all-wheel drive and 158 horsepower, feature an independent rear suspension using double wishbones instead of

5616-593: The United States are included in the Corolla's total, which meant its sales figures in the US is unknown. Compact car In Japan, small size passenger vehicle is a registration category that sits between kei cars and regular cars, based on overall size and engine displacement limits. The United States Environmental Protection Agency (EPA) Fuel Economy Regulations for 1977 and Later Model Year (dated July 1996) includes definitions for classes of automobiles. Based on

5720-481: The XRS has a weight distribution of 59/41 (front/rear), which may result in understeer when driven hard. It weighs in at a relatively light 2,800 lb (1,300 kg). Not a trim level, the M-Theory edition was a 2007-only appearance package with an exclusive "Speedway Blue" color. For US$ 1,500 , a customer got 17-inch Caldina wheels, a chrome exhaust tip, a numbered plaque (1 of 2500), four wheel disc brakes, and

5824-491: The actual increase was $ 2,445, since AWD only came with an automatic transmission). Adding AWD brought the car's curb weight of 2,679 lb (1,215 kg) up to 2,943 lb (1,335 kg) and decreased power by 7 hp (5 kW) and 7 lb⋅ft (9 N⋅m). In 2004, the price of a base model remained unchanged, but by the last year of production, 2008, it had risen to $ 15,510. The Matrix's XR mid-grade trim level added features like color-matched mirrors and door handles,

5928-461: The base model (chassis code ZRE142) and a 2,362 cc (2.362 L; 144.1 cu in) 2AZ-FE for the S and XRS trims. The former is offered with either a five-speed manual or four-speed automatic transmission , while the larger engine is equipped with either a manual or automatic five-speed transmission. In addition, the S trim can be equipped with a four-speed automatic and all-wheel drive . Canadian buyers are offered in four trim levels:

6032-758: The beginning of a downsizing of all vehicles so that cars such as the AMC Concord and the Ford Fairmont that replaced the compacts were re-classified as mid-size, while cars inheriting the size of the Ford Pinto and Chevrolet Vega (such as the Ford Escort and Chevrolet Cavalier ) became classified as compact cars. Even after the reclassification, mid-size American cars were still far larger than mid-size cars from other countries and were more similar in size to cars classified as "large cars" in Europe. It would not be until

6136-480: The brake gets hot when stopping. This is acceptable as there is sufficient time for cooling, where the maximum braking energy is very predictable. Should the braking energy exceed the maximum, for example during an emergency occurring during take-off, aircraft wheels can be fitted with a fusible plug to prevent the tire bursting. This is a milestone test in aircraft development. For automotive use, disc brake discs are commonly made of grey iron . The SAE maintains

6240-628: The brake is hot. In racing and high-performance road cars, other disc materials have been employed. Reinforced carbon discs and pads inspired by aircraft braking systems such as those used on Concorde were introduced in Formula One by Brabham in conjunction with Dunlop in 1976. Carbon–carbon braking is now used in most top-level motorsport worldwide, reducing unsprung weight , giving better frictional performance and improved structural properties at high temperatures, compared to cast iron. Carbon brakes have occasionally been applied to road cars, by

6344-586: The brakes' superior performance over rivals equipped with drum brakes . Mass production began with the 1949–1950 inclusion in all Crosley production, with sustained mass production starting in 1955 Citroën DS . Disc brakes offer better stopping performance than drum brakes because the disc is more readily cooled. Consequently, discs are less prone to the brake fade caused when brake components overheat. Disc brakes also recover more quickly from immersion (wet brakes are less effective than dry ones). Most drum brake designs have at least one leading shoe, which gives

Rear disc calipers may be mounted above (e.g. BMW R1100S ) or below (e.g. Yamaha TRX850 ) the swinging arm: a low mount provides for a marginally lower center of gravity, while an upper siting keeps the caliper cleaner and better-protected from road obstacles. One problem with motorcycle disc brakes is that when

6552-499: The cars, and Crosley-based specials, popular in SCCA H-Production and H-modified racing in the 1950s. The Crosley disc was a Goodyear -Hawley design, a modern caliper "spot" type with a modern disc, derived from a design from aircraft applications. Chrysler developed a unique braking system, offered from 1949 until 1953. Instead of the disc with caliper squeezing on it, this system used twin expanding discs that rubbed against

6656-527: The casting process). The weight and power of the vehicle determine the need for ventilated discs. The "ventilated" disc design helps to dissipate the generated heat and is commonly used on the more heavily loaded front discs. Discs for motorcycles, bicycles, and many cars often have holes or slots cut through the disc. This is done for better heat dissipation , to aid surface-water dispersal, to reduce noise, to reduce mass, or purely for non-functional aesthetics. Slotted discs have shallow channels machined into

6760-564: The combined passenger and cargo volume, compact cars are defined as having an interior volume index of 100–109 cu ft (2.8–3.1 m ). The beginnings of U.S. production of compact cars were the late 1940s prototypes of economy cars, including the Chevrolet Cadet and the Ford Light Car. Neither car reached production in the U.S., however Ford SAF in France bought the plans of

6864-402: The cost is not prohibitive. They are also found in industrial applications where the ceramic disc's lightweight and low-maintenance properties justify the cost. Composite brakes can withstand temperatures that would damage steel discs. Porsche 's Composite Ceramic Brakes (PCCB) are siliconized carbon fiber, with high-temperature capability, a 50% weight reduction over iron discs (hence reducing

6968-420: The disc to aid in removing dust and gas. Slotting is preferred in most racing environments to remove gas and water and deglaze brake pads. Some discs are both drilled and slotted. Slotted discs are generally not used on standard vehicles because they quickly wear down brake pads; however, removing of material is beneficial to race vehicles since it keeps the pads soft and avoids vitrification of their surfaces. On

7072-405: The disc. Friction causes the disc and attached wheel to slow or stop. The brake disc is the rotating part of a wheel's disc brake assembly, against which the brake pads are applied. The material is typically gray iron , a form of cast iron . The design of the discs varies. Some are solid, but others are hollowed out with fins or vanes joining the disc's two contact surfaces (usually included in

7176-484: The first European cars sold to the public to have disc brakes, fitted to all four wheels. The Jaguar C-Type racing car won the 1953 24 Hours of Le Mans , the only vehicle in the race to use disc brakes, developed in the UK by Dunlop , and the first car at Le Mans ever to average over 100 mph. "Rivals' large drum brakes could match discs' ultimate stopping, but not their formidable staying power." Before this, in 1950,

7280-592: The friction surface, the balls would be forced up the holes forcing the discs further apart and augmenting the braking energy. This made for lighter braking pressure than with calipers, avoided brake fade, promoted cooler running, and provided one-third more friction surface than standard Chrysler twelve-inch drums. Today's owners consider the Ausco-Lambert very reliable and powerful, but admit its grabbiness and sensitivity. In 1953, 50 aluminum-bodied Austin-Healey 100S (Sebring) models, built primarily for racing, were

7384-594: The inner surface of a cast-iron brake drum, which doubled as the brake housing. The discs spread apart to create friction against the inner drum surface through the action of standard wheel cylinders . Because of the expense, the brakes were only standard on the Chrysler Crown and the Town and Country Newport in 1950. They were optional, however, on other Chryslers, priced around $ 400, at a time when an entire Crosley Hot Shot retailed for $ 935. This four-wheel disc brake system

7488-608: The machine on which Tom Sheard rode to victory in the 1923 Senior TT . Successful application began on railroad streamliner passenger trains, airplanes, and tanks before and during World War II. In the US, the Budd Company introduced disc brakes on the General Pershing Zephyr for the Burlington Railroad in 1938. By the early 1950s, disc brakes were regularly applied to new passenger rolling stock. In Britain,

7592-518: The major U.S. car manufacturers made a push toward compact cars, resulting in the introduction of the Studebaker Lark , Chevrolet Corvair , Ford Falcon , and Plymouth Valiant . These models also gave rise to compact vans built on the compact car platforms, such as the Studebaker Zip Van, Chevrolet Corvair Greenbrier , Ford Econoline , and Dodge A100 . During the 1960s, compacts were

7696-515: The modern ceramic brake was made by British engineers for TGV applications in 1988. The objective was to reduce weight, and the number of brakes per axle, as well as provide stable friction from high speeds and all temperatures. The result was a carbon-fiber-reinforced ceramic process which is now used in various forms for automotive, railway, and aircraft brake applications. Due to the high heat tolerance and mechanical strength of ceramic composite discs, they are often used on exotic vehicles where

7800-399: The more common form in most passenger vehicles. However, many (lightweight vehicles) use drum brakes on the rear wheels to keep costs and weight down as well as to simplify the provisions for a parking brake . This can be a reasonable compromise because the front brakes perform most of the braking effort. Many early implementations for automobiles located the brakes on the inboard side of

7904-490: The motorcycle during braking. Modern sport bikes typically have twin large front discs, with a much smaller single rear disc. Bikes that are particularly fast or heavy may have vented discs. Early disc brakes (such as on the early Honda Fours and the Norton Commando ) sited the calipers on top of the disc, ahead of the fork slider. Although this gave the brake pads better cooling, it is now almost universal practice to site

8008-417: The outside diameter of the disc. The disc is spun. The difference between the minimum and maximum value on the dial is called lateral run-out. Typical hub/disc assembly run-out specifications for passenger vehicles are around 0.002 in (0.0508  mm ). Runout can be caused either by deformation of the disc itself or by runout in the underlying wheel hub face or by contamination between the disc surface and

8112-679: The passenger and cargo compartments were introduced in the late 1970s. In the early 1970s, the domestic automakers introduced even smaller subcompact cars that included the AMC Gremlin , Chevrolet Vega , and Ford Pinto . In 1973, the Energy Crisis started, which made small fuel-efficient cars more desirable, and the North American driver began exchanging their large cars for the smaller, imported compacts that cost less to fill up and were inexpensive to maintain. The 1977 model year marked

8216-436: The piston seal has a square cross-section, also known as a square-cut seal. As the piston moves in and out, the seal drags and stretches on the piston, causing the seal to twist. The seal distorts approximately 1/10 of a millimeter. The piston is allowed to move out freely, but the slight amount of drag caused by the seal stops the piston from fully retracting to its previous position when the brakes are released, and so takes up

8320-630: The popular Volkswagen Beetle . Compact cars were also the basis for a new small car segment that became known as the pony car , named after the Ford Mustang , which was built on the Falcon chassis. At that time, there was a distinct difference in size between compact and full-size models. Early definitions of vehicle size class were based on wheelbase, with models under 111 inches as compact, 111 to 118 inches intermediate, and over 118 inches as full size, at least until EPA classes based on interior volume of

8424-651: The previous GM -sourced radio. Two 1.8 L four-cylinder engines were offered in the Matrix: the 1ZZ-FE used in the Corolla, which originally made 130 horsepower (97  kW ) in 2003 through 2005 models, but was reduced to 126 horsepower (94 kW) in 2006, and the performance-oriented 2ZZ-GE taken from the Toyota Celica GT-S, which produced 164 horsepower (122 kW) (previously 180 horsepower (130 kW) in 2003, 173 hp (129 kW) in 2004, and 170 horsepower (130 kW) in 2005). The 2006 drop in power

8528-442: The road, drilled or slotted discs still have a positive effect in wet conditions because the holes or slots prevent a film of water from building up between the disc and the pads. Two-piece discs are when the center mounting part of the disc is manufactured separately from the outer friction ring. The central section used for fitment is often called the bell or hat because of its shape. It is commonly manufactured from an alloy such as

8632-419: The slack caused by the wear of the brake pads, eliminating the need for return springs. In some rear disc calipers, the parking brake activates a mechanism inside the caliper that performs some of the same functions. Discs are usually damaged in one of four ways: scarring, cracking, warping, or excessive rusting. Service shops will sometimes respond to any disc problem by changing out the discs entirely, This

8736-538: The smallest class of North American cars, but they had evolved into only slightly smaller versions of the 6-cylinder or V8-powered six-passenger sedan. They were much larger than compacts (and sometimes even mid-sizers) by European manufacturers, which were typically five-passenger four-cylinder engine cars. Nevertheless, advertising and road tests for the Ford Maverick and the Rambler American made comparisons with

8840-408: The switch assembly with a special fluorine grease. On August 5, 2013, Toyota announced an end to production of the Matrix for the US market after the 2013 model year due to declining sales, and that there were no plans to replace it with another vehicle. The Canadian market continued for the 2014 model year, with those assembled in Cambridge, Ontario by Toyota Motor Manufacturing Canada . The Matrix

8944-518: The system impractical. In 1921, the Douglas motorcycle company introduced a form of disc brake on the front wheel of their overhead-valve sports models. Patented by the British Motorcycle & Cycle-Car Research Association, Douglas described the device as a "novel wedge brake" working on a "beveled hub flange". A Bowden cable operated the brake. Front and rear brakes of this type were fitted to

9048-399: The thickness variation. Machining on-car with the proper equipment can also eliminate lateral run-out due to hub-face non-perpendicularity. Incorrect fitting can distort (warp) discs. The disc's retaining bolts (or the wheel/lug nuts, if the disc is sandwiched in place by the wheel) must be tightened progressively and evenly. The use of air tools to fasten lug nuts can be bad practice unless

9152-807: The time, while the Datsun was an all-new vehicle. These vehicles were followed by the Hino Contessa in 1961, the Isuzu Bellett , Daihatsu Compagno and Mazda Familia in 1963, the Mitsubishi Colt in 1965, and the Nissan Sunny , Subaru 1000 , and Toyota Corolla in 1966. Honda introduced its first four-door sedan in 1969, called the Honda 1300 . In North America, these cars were classified as subcompact cars . By 1970, Nissan released its first front-wheel-drive car which

9256-479: The underlying hub mounting surface. Determining the root cause of the indicator displacement (lateral runout) requires the disassembly of the disc from the hub. Disc face runout due to hub face runout or contamination will typically have a period of 1 minimum and 1 maximum per revolution of the brake disc. Discs can be machined to eliminate thickness variation and lateral run-out. Machining can be done in situ (on-car) or off-car (bench lathe). Both methods will eliminate

9360-399: The vehicle be able to maintain a maximum speed over 100 km/h (62 mph), weigh below 400 kg (882 lbs), fuel consumption at 30 km/L (85 mpg ‑imp ; 71 mpg ‑US ) or more, at an average speed of 60 km/h (37 mph) on a level road, and not require maintenance or significant service for at least 100,000 km (62,000 mi). This established

9464-451: The vehicle's central hydraulic system. This model went on to sell 1.5 million units over 20 years with the same brake setup. Despite early experiments in 1902, from British Lanchester Motor Company , and in 1949 from Americans Chrysler and Crosley , the costly, trouble-prone technology was not ready for mass production. Attempts were soon withdrawn. The Jensen 541 , with four-wheel disc brakes, followed in 1956. Triumph exhibited

9568-488: The vehicle's unsprung weight), a significant reduction in dust generation, substantially extended maintenance intervals, and enhanced durability in corrosive environments. Found on some of their more expensive models, it is also an optional brake for all street Porsches at added expense. They can be recognized by the bright yellow paintwork on the aluminum six-piston calipers. The discs are internally vented much like cast-iron ones, and cross-drilled. In automotive applications,

9672-655: The version. Toyota of Mexico has notified PROFECO that in the Mexican market exists 618 vehicles in addition to these three recalled vehicles. The replacing campaign will go due November 22. Initially rumored by Toyota and auto news media as a Matrix replacement named the Blade, the second generation Matrix was unveiled on October 31, 2007, at the Specialty Equipment Market Association ( SEMA ) show in Las Vegas , and

9776-451: The war, technological progress began in 1949, with caliper-type four-wheel disc brakes on the Crosley line and a Chrysler non-caliper type. In the 1950s, there was a demonstration of superiority at the 1953 24 Hours of Le Mans race, which required braking from high speeds several times per lap. The Jaguar racing team won, using disc brake-equipped cars, with much of the credit being given to

9880-474: The wheel, bike disc brakes are in the airstream and have optimum cooling. Although cast iron discs have a porous surface that provides superior braking performance, such discs rust in the rain and become unsightly. Accordingly, motorcycle discs are usually stainless steel, drilled, slotted, or wavy to disperse rainwater. Modern motorcycle discs tend to have a floating design whereby the disc "floats" on bobbins and can move slightly, allowing better disc centering with

9984-459: The wheels, which helps ensure a free flow of cooling air. Some modern passenger rail cars, such as the Amfleet II cars , use inboard disc brakes. This reduces wear from debris and provides protection from rain and snow, which would make the discs slippery and unreliable. However, there is still plenty of cooling for reliable operation. Some airplanes have the brake mounted with very little cooling, and

10088-417: Was built by Auto Specialties Manufacturing Company (Ausco) of St. Joseph, Michigan , under patents of inventor H.L. Lambert, and was first tested on a 1939 Plymouth . Chrysler discs were "self-energizing," in that some of the braking energy itself contributed to the braking effort. This was accomplished by small balls set into oval holes leading to the braking surface. When the disc made initial contact with

10192-440: Was detuned. Again, the car's price for its second year stayed the same, but in the four years after that, it rose to $ 16,990. For US$ 18,750- , the top-of-the-line model came standard with four-wheel disc brakes and six speakers. Also included on all XRS models were anti-lock brakes with Electronic Brakeforce Distribution , 16-inch alloy wheels, and cruise control . In 2003, 17-inch wheels could be had, but only on cars without

10296-404: Was due to new testing standards, and not a change in the engine's actual performance. In late 2006, Toyota discontinued use of the 2ZZ-GE engine and dropped the XRS from the Matrix lineup to be temporarily replaced by the M-Theory edition. Like each year of the XRS model, the M-Theory was a limited production run of 2500 cars. All wheel drive was also available from 2003 to 2006 when coupled to

10400-456: Was first available at dealerships in February 2008, as a 2009 model. The sibling of the Matrix, the Vibe, was also upgraded, but production of that model ended after 2009 when the entire Pontiac brand was retired. In the United States, three trim levels ( Standard [base], S and XRS ) are offered, as well as two inline-four engines : a 1,797 cc (1.797 L; 109.7 cu in) 2ZR-FE for

10504-598: Was originally developed by Prince Motor Company which had merged with Nissan in 1966. This was introduced in 1970 as the Nissan Cherry . In 1972, the Honda Civic appeared with the CVCC engine that was able to meet California emission standards without the use of a catalytic converter . In Pakistan, the concept of compact cars is significant. The most common cars tend to be Kei cars . Popular compact cars in recent times are

10608-574: Was positioned as a sporty hatchback counterpart of the North American Corolla and was counted as a variant of it in Toyota's sales figures. Although identical mechanically, and nearly as much internally, the Matrix and Vibe had different sheetmetal and exterior trim designed by their respective brands. Both vehicles are narrow, tall station wagons styled in a quasi- SUV fashion (called a crossover utility vehicle or "CUV" by Toyota) and marketed to

10712-466: Was the Michele Pirro incident at Mugello, Italy 1 June 2018. At least one manufacturer has developed a system to counter the pads being forced away. A modern development, particularly on inverted ("upside down", or "USD") forks is the radially mounted caliper. Although these are fashionable, there is no evidence that they improve braking performance or add to the fork's stiffness. (Lacking the option of

10816-546: Was then discontinued in Canada and was not offered for the 2015 model year. Toyota continued to sell a range of compact hatchbacks in North America through its Scion brand. On September 1, 2016, "the Scion brand transitioned to Toyota." For the 2017 model year, the Corolla iM would be the successor of the Matrix. For the 2019 model year, the newest iteration has been released as the Corolla hatchback . Matrix sales figures in
