The hazard
On certain trailers, the diaphragm for the Tramec Sloan 51102 quick release valve of the emergency air brake system can degrade and develop pin hole leaks under constant pressure, allowing air to escape. This could result in unintended gradual park/spring brake application, causing overheating or unintended spring brake application, and increase the risk of a crash causing injury and/or property damage. Correction: Cheetah will supply repair kits for the installation of heavy duty diaphragms in the quick release valves.
