What's wrong?
The Bendix SR5 spring brake valve on the 2015 Wilson CD-1080 and DWH-550 trailers is part of the air brake system that controls the trailer's spring parking brakes. When the trailer is parked, the valve helps release air pressure so the spring brakes apply and hold the trailer in place.
On affected trailers, an internal check-valve port inside the SR5 valve was milled to the wrong diameter. That machining error lets air leak through the valve instead of routing pressure the way the brake system expects. During parking, the spring brakes can apply later than intended, which means the trailer does not settle into its parked brake hold as quickly as designed.
The warning sign is an air leak. When the trailer is uncoupled, the leak is heard or seen at the supply, red gladhand. When it is coupled to a tractor, the leak is heard from the park control valve exhaust or the tractor protection valve.

What's the safety risk?
A delayed spring brake application can allow a decoupled trailer to roll away, increasing the risk of a crash or injury.

Repair will be free at any franchised Wilson dealer once available.
