Removal Procedure
Warning:
Refer to Brake Dust Warning Brake Dust Warning.
Caution:
Support the brake caliper with heavy mechanic 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.
1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle Service and Repair.
2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation Service and Repair.
3. Remove the brake caliper bracket bolts (1).
4. Without disconnecting the brake caliper hose, remove the brake caliper and bracket assembly and support with heavy mechanics wire or equivalent.
5. If installing the original brake rotor, mark the relationship of the rotor to the wheel hub.
6. Remove the brake rotor screw (1) and the brake rotor.
7. If the brake rotor is to be machined, check the thickness variation measurement. Refer to Brake Rotor Thickness Variation Measurement Brake Rotor Thickness Variation Measurement.
Installation Procedure
1. If installing a new brake rotor, clean the friction surfaces of the brake rotor with denatured alcohol.
2. Using the CH-41450-A - Wheel Hub Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
3. Using the CH-41013 - Rotor Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface of the rotor to the hub/axle flange.
4. If installing the original brake rotor, align the rotor to the wheel hub as noted during removal.
Caution:
Refer to Fastener Caution Fastener Caution.
5. Install the brake rotor screw (1) and tighten to 10 Nm (89 lb in).
6. Position the brake caliper and bracket assembly to the vehicle.
Note:
If reusing the caliper bracket bolts the threads of the caliper bracket bolts and the threads of the knuckle mounting holes must be free of residue and debris prior to application of threadlocker in order to ensure proper adhesion and fastener retention.
7. Prepare the bolts and the threaded holes for assembly:
* Thoroughly clean the residue from the bolt threads by using denatured alcohol or equivalent and allow to dry.
* Thoroughly clean the residue from the threaded holes with denatured alcohol or equivalent and allow to dry.
* Apply threadlocker GM P/N 12345493 (Canada P/N 10953488), or equivalent to 2/3 of the threaded length of the lower caliper bracket bolts.
* Ensure there are no gaps in the threadlocker along the length of the filled area of the bolts.
* Allow the threadlocker to cure approximately 10 minutes before installation.
8. Install the brake caliper bracket bolts (1) and tighten to 120Nm (89 lb ft).
9. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation Service and Repair.
