The problem
THE AUTOMATIC APPLY TRANSMISSION MOUNTED PARKING BRAKE LEVER PIVOT BOLT "FINGER" MAY BE LOOSE.
Risk
THE LOOSE PIVOT BOLT COULD ALLOW THE PARKING BRAKES TORELEASE AFTER THEY HAVE BEEN SET MANUALLY; IF THE BOLT FALLS OFF WHEN THEAUTOMATIC APPLY PARKING BRAKE IS SET, THERE IS INSUFFICIENT BRAKING TO HOLD THEVEHICLE IF IT IS PARKED ON AN INCLINE. BOTH OF THESE CONDITIONS COULD RESULT INVEHICLE MOVEMENT WITHOUT PRIOR WARNING AND POSSIBLY IN AN ACCIDENT.
What owners should do
TORQUE PIVOT BOLT TO SPECIFICATIONS.
