Description of Recall:
On certain light duty trucks equipped with 4-wheel disc brakes, the Antilock Brake System (ABS) motor contains 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, increasing the likelihood of a crash.
Action Need To Fix It:
Dealers will replace the brake pressure module valve assembly. The manufacturer has reported that owner notification will begin during April 2000. Owners who do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020 or GMC at 1-800-462-8782.
