Modern-style  scion disc brakes first appeared on the low-volume Crossly Hotshot in 1949, although they had to be discontinued in 1950 due to design problems.[1] Chrysler's Imperial also xb offered a type of disc brake from 1949 through 1953, though in this instance they were enclosed with dual internal-expanding, full-circle pressure plates. Reliable xb modern disc brakes were developed in the UKby Dunlop and first appeared in 1953 on the Jaguar C-Type racing car. The Citroën DS of 1955, with powered inboard front disc brakes, and the 1956 Triumph TR3 were the first European production cars to feature modern disc brakes.[2] The first xb production car to feature disc brakes at all 4 corners was the Austin-Healey 100S in 1954. [3]The first British company to market a production saloon fitted with disc brakes to all four wheels was Jensen Motors Ltd with the introduction of a Deluxe version of the Jensen 541 with Dunlop disc brakes. [4]The next American production cars to be fitted with disc brakes were the 1963 Studebaker Avanti[5] (optional on other Studebaker models), standard equipment xb on the 1965 Rambler Marlin (optional on other AMC models), and the 1965 Chevrolet CorvetteStingray (C2) disc.

• Many higher performance brakes have holes xb drilled through them disc xb. This is known as cross-drilling and xb was originally done in the 1960s on racing cars. Brake pads will outgas and under use may create boundary layer of gas between the pad and the disc hurting braking performance. Cross-drilling was created to provide the gas someplace xb to escape. Although modern brake pads xb seldom suffer from outgassing problems, water residue may build up after a vehicle passes through a puddle and impede braking performance. For this reason, and for heat dissipation xb purposes, cross drilling is still used on xb some braking xb components, but is not favored for racing or other hard use as the holes are a source of stress cracks under xb severe condit

In racing and very high performance road cars, disc other disc materials have been employed. Reinforced xb carbon discs and pads inspired by aircraft braking systems were introduced in Formula One by Braham in conjunction with Dunlop in 1976.[6] Carbon-Carbon braking is now used in most top-level motorsport worldwide, reducing unsparing 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 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 xb
