Removal Procedure





The use of GM brake pad material will help to maintain a balance between the front and the rear brake performance. In addition, the use of GM brake pad material will provide the proper brake balance for the purposes of stopping distance and control over the full range of operating conditions. The installation of any front brake pads or rear brake shoe material with a performance different from that of the suggested GM replacement parts for this vehicle may change the intended brake balance of this vehicle.
1. Raise the vehicle. Support the vehicle with suitable safety stands. Refer to Vehicle Lifting.
2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation.
3. Remove the front brake caliper from the front brake rotor. Do not disconnect the brake hose from the caliper. Refer to Brake Caliper Replacement.

^ The front brake pad retainer spring is already staked to the brake pad.
^ The front brake pad must lay flat against the front brake caliper piston.





3. Install the front outboard brake pad with the wear indicator at the leading edge of the front brake pad during forward wheel rotation. The back of the front brake pad must lay flat against the front brake caliper.
4. Install the front brake caliper onto the front brake rotor. Refer to Brake Caliper Replacement.
5. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation.

Important: After lowering, but before moving, the vehicle, pump the brake pedal until it is firm. Check the fluid level in the brake master cylinder after pumping the brakes.
