The air brake system uses compressed air to apply pressure to brake pads to stop large heavy vehicles. It has several main components including a brake valve to control air flow, governors to regulate air pressure, air tanks to store compressed air, air compressors to fill the tanks, brake chambers that use air pressure to engage the brakes, and slack adjusters to ensure proper brake clearance.

in which compressed air pressing on a piston is used
to apply the pressure to the brake pad needed to
stop the vehicle.
