How Air Brakes Work
How do air brakes work. When the engine starts, the brake compressor starts to pressurize the air. The compressor governor then sends this compressed air at a set pressure to the air storage tank. The tank normally has some amount of air from the previous cycle, so even if the engine is shut off, the brakes will still function as normal.
