The defect
MANAC, Inc. (MANAC) is recalling certain model year 2016 Flatbed trailers manufactured September 1, 2014, to September 30, 2014, and 2017-2018 Van trailers manufactured January 1, 2015, to March 31, 2016. These trailers are equipped with certain Bendix SR5 spring brake valves which may have been improperly machined which could cause a delay of application of the spring brakes while parking.
The risk
If there is a delay of the spring brake application, the trailer may roll away after it has decoupled from the tractor, increasing the risk of a crash or injury.
