Brake Rotor Replacement - Front

Removal Procedure

1. Block the wheels.
2. Apply the parking brake.
3. Raise the vehicle. Support the vehicle with suitable safety stands. Refer to Vehicle Lifting.
4. Remove the tire and wheel.

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.

5. Remove the brake caliper.
6. Remove the brake rotor.





7. Remove the bolts that mount the front brake rotor to the hub.
8. Remove the brake rotor from the hub.

Installation 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 P/N 123777981 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. Install the brake rotor to the hub.

Notice: Refer to Fastener Notice in Service Precautions.





2. Install the bolts that mount the brake rotor to the hub, or the wheel.
Tighten the brake rotor bolts (5/8 in OD-5 bolt pattern) to 256 Nm (189 ft. lbs.).

Important: Ensure that the threads are clean and greaseless before applying the threadlocker.

3. Apply 272 Threadlocker GM P/N 12345493, or the equivalent, to the threads of each brake rotor bolt.
4. Install the brake rotor.
5. Inspect the brake rotor for runout after installation.
6. Clean both sides of the brake rotor with Brake Parts Cleaner GM P/N 12345754 or the equivalent.
