Massive recall affects more than 30,000 trailers with parking brake issue

Trailer manufacturers are recalling tens of thousands of trailers due to an issue with Bendix spring valves. Approximately 10 manufacturers have recalled a total of more than 30,000 trailers in response to an equipment recall Bendix announced in June.

On June 8, the National Highway Traffic Safety Administration sent out a recall notice regarding an issue with nearly 195,000 Bendix SR-5 trailer spring brake valves. According to NHTSA, brake valves were improperly machined without a radius on the internal check valve seat, causing a delay of application of the spring brakes while parking.

More than a month later, NHTSA has sent out a recall notice with specific makes and models of trailers affected by the recall. Affected trailers include:

The SR-5 valve is a reservoir-mounted trailer valve that can control four spring brake actuators during parking or emergency applications, a NHTSA safety recall report explains. A trailer will have an audible air leak from the dash mounted park control valve or red gladhand when it is disconnected, prior to decoupling when a slow-to-park situation occurs. This leakage will continue until the trailer reservoirs and spring brake chambers are depleted of air pressure.

Remedies for this recall are still under development. Expected recall dates vary by manufacturer. Owners of potentially affected trailers can contact NHTSA at 888-327-4236. NHTSA recall number for the original Bendix equipment recall is 16E-045.
