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.
Anti-lock brakes enable ESC to slow down individual wheels. Many ESC systems also incorporate a traction control system (TCS or ASR), which senses drive-wheel slip under acceleration and individually brakes the slipping wheel or wheels and/or reduces excess engine power until control is regained.
A Combined Braking System therefore distributes the brake force also to the non-braked wheel to lower the possibility of a lock-up, increase deceleration and reduce suspension pitch. With a single [rear] CBS the brake pressure applied on the rear brake (pedal) is simultaneously distributed to the front wheel.
R90 calls for linings to be tested for speed sensitivity, cold performance, and replacement Brake pads and brake shoes are permitted to deviate from the frictional characteristics of their original-equipment counterparts by not more than 15%. [2] In addition, R90 requires tamper-evident, sealed packaging for replacement brake linings. [1]

It consists of a shaft, usually around 4 to 25 inches long, turned at one end by means of an air-powered brake booster and lever with an S-shaped cam at the wheel end. Turning the shaft pushes the brake shoes against the drum, producing friction. The design allows bulky air cylinders to be located outside of the wheel.
