Air Brake Parts

Project Details

The five main components of an “elementary” air brake system and their purposes are:

  1. Compressor: to build up and maintain air pressure
  2. Reservoirs: to store the compressed air
  3. Foot valve: to draw compressed air from reservoirs when it is needed for braking
  4. Brake chambers: to transfer the force of compressed air to mechanical linkages
  5. Brake shoes and drums or brake rotors and pads: to create the friction needed to stop the vehicle
