VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS EQUIPPED WITH 4-WHEEL DISC BRAKES. SOME OF THESE VEHICLES HAVE AN ANTILOCK BRAKE SYSTEM "ABS" MOTOR CONTAINING AN OUT-OF-SPECIFICATION SPRING CLIP. THIS CLIP COULD ALLOW THE MOTOR BEARING TO BECOME MISALIGNED. IF MISALIGNMENT OCCURS, EVENTUALLY THE ABS WOULD BE NON-FUNCTIONAL.

THE BASE BRAKES WOULD REMAIN FULLY FUNCTIONAL, BUT THE DYNAMIC REAR PROPORTIONING "DRP" SYSTEM, WHICH OPTIMIZES FRONT TO REAR BRAKE BALANCE, WOULD BECOME INOPERATIVE.

DEALERS WILL REPLACE THE BRAKE PRESSURE MODULE VALVE ASSEMBLY.
