A look at the movements and states of operation of the air brake relay.
Relays are fitted to an air braking system for larger vehicles to speed up the application and release of the brakes, minimising brake lag, which is the time it takes between the driver operating the controls (park brake/foot brake valve) and the action actually happening at the brakes.
