Product Description
Relay Valve
Features & Benefits
- Delivers reservoir air straight to its chambers on signal
- Uses standard Bendix service kits for later seal work
- Long lines from the cab add lag that a relay valve removes
- Tractor and trailer rear axles are where relay valves usually sit
Bendix Air Brake Relay Valve
In search of a relay valve to bring rear-axle braking back in step with the front? The Bendix Air Brake Relay Valve does that, delivering reservoir air straight to its chambers when the foot valve signals. Short air runs to the chambers mean the Bendix K040979 applies and releases the rear brakes without the lag of a long line from the cab. Matching crack pressure to the original keeps the axles sharing the braking load evenly.
