3. Inner brake pad (7). Wipe outside surface of caliper piston boot (8) with denatured alcohol.

Compressing Front Brake Caliper Piston:

Lifting Front Brake Caliper Piston Boot:

NOTE: Push caliper piston (9) into housing bore. Using a large C-clamp positioned on the caliper housing (12) and inside the piston well. Tighten the clamp slowly to press the caliper piston (9) into the housing bore. With the caliper piston (9) bottomed in the housing bore, lift the inner edge of the piston boot (8) next to the piston (9) and press out any trapped air. Piston boot (8) must lay flat.

INSTALL OR CONNECT

Installing Front Disc Brake Inner Pad:

NOTE: GM replacement brake pads are recommended for all GM vehicles to maintain the balance between front and rear brake performance. GM replacement brake parts have been carefully selected to provide the proper brake balance for purposes of both stopping distance and controllability over the full range of operating conditions. Installation of front or rear brake pads other than GM replacement parts can change the intended brake balance of this vehicle.
