While the GM car was fully tested, the Pontiac concept was not.
Truck air-actuated disc brake. An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to both release the parking/emergency brakes in order to move the vehicle, and also to apply pressure to the brake pads or brake shoes to slow and stop the vehicle.
Many high-speed vehicles use disc brakes, and many European heavy vehicles use disc brakes. [3] Many U.S. and third-world heavy vehicles use drum brakes due to their lower purchase price. On heavy vehicles, air drag is often small compared to the weight, so the brakes dissipate proportionally more energy than on a typical car or motorcycle.
The S-cam foundation brake is being used in over 85% of vehicles in the U.S. that run with air brakes. [1] S-cam's are only used with drum brakes because the cam pushes on the brakes which rubs against the rotating drum, and thus slowing the vehicle. [2] Drum brakes are favored on bigger vehicles because they allow more surface area in brake ...
