1952 Jaguar C-Type: Disc Brakes
Most brakes work by turning the energy of a vehicle's momentum into heat that dissipates into the atmosphere. And the most efficient brakes for doing that are disc brakes, which were first used in racing on the 24 Hours of Le Mans winning Jaguar C-Type in 1952. Since then, braking materials and caliper designs have changed, but the basic concept of a rotor exposed to the air clamped on either side has remained unchanged. And four-wheel disc brakes have now replaced the previous drum brake design on almost all new cars.
