Speed up brake application on axles far from the foot valve with the Bendix Air Brake Relay Valve. It uses a small control signal from the foot valve to send full reservoir air straight to the chambers it serves. Mounting it close to those chambers shortens the distance air travels, so the rear brakes apply and release in step with the front. Matching crack pressure to the original valve lets the Bendix 801305 keep braking balanced between axles.
