W-Car Rear Caliper Bushing Kit
This is the approved method of servicing seized four wheel disc brake rear caliper slides on GM W-body cars: the bushing driver attaches to your air hammer to remove the frozen slide; the hone cleans out the inside of the caliper slide bore; and the wire brush cleans out the caliper's seal groove. For use on 1988-current Pontiac Grand Prix, Oldsmobile Cutlass Supreme, Buick Regal and 1990-current Chevrolet Lumina.
