Removal Procedure
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
- Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
- Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
- Remove and support the caliper and bracket as an assembly with heavy mechanics wire. DO NOT disconnect the hydraulic flexible brake hose. Refer to Brake Caliper Bracket Replacement - Front .
- Remove the brake rotor.
- If the brake rotor is to be reinstalled to the vehicle, use theJ 41013 in order to clean any rust or corrosion from the hub/axle flange mating surface of the brake rotor. See Special Tools and Equipment .
- Use the J 42450-A in order to clean the wheel hub flange. See Special Tools and Equipment .
CAUTION:
Refer to Brake Dust Caution
in Cautions and Notices.
NOTE:
Any new rotor must have the protective coating removed from the friction surfaces before being placed in service. Remove the protective coating using denatured alcohol or an equivalent, and wipe the surface clean with clean cloths. Do not use gasoline, kerosene, or other oil base solvents which may leave an oily residue. This residue is damaging to the brake lining and is flammable.
NOTE:
Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
IMPORTANT:
When a brake rotor has been separated from a hub/axle flange, the mating surface of the brake rotor must be cleaned of any rust or contaminants. Failure to do this may result in lateral runout of the brake rotor, and brake pulsation.
