UNDER CERTAIN CONDITIONS, VEHICLES MAY EXPERIENCE PREMATURE REAR WHEEL SKID DURING BRAKING. REAR WHEEL SKIDDING IS MOST LIKELY TO OCCUR ON A WET OR SLICK SURFACE.

DEPENDING ON THE TRANSMISSION TYPE AND THE BRAKE COMPONENTS THAT HAVE BEEN INSTALLED, DEALERS WILL INSPECT AND REPLACE OR REPAIR, AS NECESSARY, CERTAIN FRONT BRAKE COMPONENTS, AND THE PARKING BRAKE CABLES. THE REAR BRAKE SHOES AND LININGS WILL BE REPLACED WITH PARTS THAT USE A MATERIAL WHICH GREATLY REDUCES THE LIKELIHOOD OF REAR WHEEL SKID. ACTIONS TAKEN TO THE FRONT BRAKES ARE TO ENSURE UNIFORMITY OF THE ENTIRE BRAKE SYSTEM. ACTIONS TAKEN TO THE PARKING BRAKE COMPONENTS WILL ENSURE THAT THE PERFORMANCE REQUIREMENTS, FOR KEEPING THE VEHICLE STATIONARY WHILE MANUAL TRANSMISSION EQUIPPED UNITS ARE IN NEUTRAL AND AUTOMATIC TRANSMISSION EQUIPPED UNITS ARE IN PARK, ARE MET.
