What's wrong?
The Bendix SR5 spring brake valve is part of the trailer's air brake system on affected 2015-2017 Stoughton Avw, Zgpvw, Dvw, and Avxw trailers. It helps route compressed air to the spring brake chambers, which release the brakes for travel and hold the trailer when it is parked.
On these trailers, the valve body was improperly machined. That machining error can make the valve malfunction and send air leaking back through the supply gladhand, the air-line connector between the tractor and trailer. If the valve fails while the trailer is parked, the parking brake chamber can stop holding the brakes as intended.
The warning sign is an audible hiss of air from the supply gladhand area. If you hear that leak, the brake air system is not sealing correctly.
Who's affected?
