How the work air brakes?

Air brake systems have a belt driven air compressor on the motor that feeds an air tank. The air tank has a "pop off valve" that lets off air pressure so the tank doesn't over fill with air. The air tank is connected to the brakes with tubes. In modern air brake systems the brakes are held open by the air pressure that fights springs that push the brakes closed. This is so if the system fails ( loses air pressure ) the brakes will be applied. When the operator depresses the brake peddle the air pressure is released from the brakes and the springs push them against the drum or rotor.


Do air brakes use brake fluid?

No, they use air pressure or actually the lack of air pressure to stop the vehicle. The brakes are fully on until pressure builds up in the tank releasing the brakes. When you push the brake pedal this removes air from the system and applies the brakes.
