Brake Rotor Replacement - Front

^ Tools Required
- J 41013 Rotor/Drum Flange Resurfacing Kit
- J 42450-A Wheel Hub/Flange Resurface Kit

Removal Procedure

Notice: Any new rotor must have the protective coating removed from the friction surfaces before being placed in service. Use Goodwrench Brake Parts Cleaner, GM P/N 123777981 (Canadian P/N 10953463), or the 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.





1. Raise and suitably support the vehicle. Refer to Vehicle Lifting.
2. Remove the tire and wheel assembly.

Notice: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's 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.

3. Remove and support the caliper and bracket as an assembly with heavy mechanics wire. DO NOT disconnect the hydraulic flexible brake hose.
4. Remove the brake rotor.

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.

5. If the brake rotor is to be reinstalled to the vehicle, use the J 41013 in order to clean any rust or corrosion from the hub/flange mating surface of the brake rotor.
6. Use the J 42450-A in order to clean the wheel hub flange.

Installation Procedure





1. Install the brake rotor.
2. Install the caliper bracket.
3. Install the tire and the wheel.
4. Lower the vehicle.
