11. Remove the brake rotor retaining push nuts from the wheel studs, if applicable.
12. It may be necessary to strike the end of the hub or the rotor with a deadblow hammer to separate the rotor from the hub.
13. Remove the rotor by slowly turning the rotor while pulling the rotor away from the axle.
Installation Procedure
Note: Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the hub/axle flange
and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead
to brake pulsation.
1. Use the J-42450-A - Wheel Hub Resurfacing Kit to clean all rust and contaminants from the mating surface of the hub flange.
2. Use the J-41013 - Rotor Resurfacing Kit to clean all rust and contaminants from the inside diameter of the hat section of the brake rotor to prevent
any foreign material from getting between the brake rotor and the hub flange.
3. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
4. Align the rotor to its original position on the hub, if applicable.
5. Install the rotor by slowly turning the rotor while pushing the rotor towards the axle.
6. Install the caliper and caliper bracket as an assembly.
7. Perform the following procedure before installing the brake caliper bracket bolts:
1. Remove all traces of the original adhesive patch.
2. Clean the threads of the bolts with brake parts cleaner or the equivalent and allow to dry.
3. Apply threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the threads of the bolts.
Caution: Refer to Fastener Caution See: Service Precautions/Vehicle Damage Warnings/Fastener Caution.
