Bendix 800481 is an R-12DC relay valve for air brake systems. A relay valve takes the signal from the brake pedal circuit and opens to send air to the brake chambers, then lets that air back out when the pedal is released so the brakes reset. A tired relay valve shows up as brakes that are slow to apply, a weak response from the pedal, or uneven lining wear. This is a genuine Bendix part from Pro Gear and Transmission.
