The defect
John Evans Manufacturing Co. (John Evans) is recalling certain 2017-2018 Flatbed trailers. The air brake diaphragm on these vehicles may degrade and allow the brake system air to leak from the quick release valve causing the emergency brakes to engage.
The risk
Partial or full application of the emergency brakes can cause the wheel-end to overheat or a drag slowing or stopping the vehicle, increasing the risk of a crash.
