The defect
ON CERTAIN TRUCKS EQUIPPED WITH MANIFOLD DASH VALVES WITH PUSH TO CONNECT FITTINGS USED TO CONTROL THE PARK BRAKE FUNCTION ON TRUCKS AND TRAILERS WITH AIR BRAKES, THE PARK KNOB CAN POP OUT UNEXPECTEDLY WHILE THE VEHICLE IS IN MOTION. THIS WILL EXHAUST THE AIR FROM THE PARK BRAKE SYSTEM ON THE TRAILER AND APPLY THE PARKING BRAKES.
The risk
IF THIS CONDITION IS NOT NOTICED, THE DRIVER COULD LOSE CONTROL OF THE VEHICLE, POSSIBLY RESULTING IN A VEHICLE CRASH.
The remedy
HALDEX HAS NOTIFIED ITS CUSTOMERS TO MAKE ARRANGEMENTS TO HAVE THE VALVE INSPECTED AND, IF NECESSARY, REPLACED FREE OF CHARGE. OWNER NOTIFICATION IS EXPECTED TO BEGIN DURING JANUARY 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT HALDEX BRAKE SYSTEMS AT 816-801-2641 OR MACK AT 1-610-709-3337.
