EQUIPMENT
Because of the improper orientation, in the event of an air leakage at the isolation/vent valve, the 5th wheel jaw may release, unexpectedly releasing the trailer from the tractor, increasing the risk of a vehicle crash.

SERVICE BRAKES
Brake assembly fractures may result in an inoperative brake on the affected wheel. This will cause the vehicle to pull to one side unexpectedly during breaking and/or increase the stopping distance. Either result may increase the risk of a vehicle crash.
