The problem
TRUCKS WERE BUILT WITH INCORRECT REAR BRAKE ASSEMBLIES. CONSEQUENCE OF DEFECT: A TENDENCY FOR REAR BRAKE LOCKUP WOULD EXIST PARTICULARLY DURING HEAVY BRAKE APPLICAION WITH A LIGHTLY LOADED TRUCK. ALSO, INCREASED STOPPING DISTANCE WOULD BE REQUIRED IF THE BRAKE MODULATION (PUMPING THE BRAKES) IS USED TO CONTROL THE VEHICLE DURING A HARD BRAKE STOP.
What owners should do
REPLACE REAR BRAKE ASSEMBLIES.
