hydraulic brake flexible hose from the caliper.
7. Remove the rotor retaining push nuts from the wheel studs, if applicable.
8. 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.
9. Remove the rotor by slowly fuming the rotor while pulling the rotor away from the axle.
Installation Procedure
Notice: Whenever the brake rotor has been separated from the wheel bearing flange, clean any rust or foreign material from the mating surface of the
rotor and flange with the J42450 hub cleaning kit. Failure to do this may result in increased lateral runout of the rotor and brake pulsation.
1. Use the J42450-A to clean all rust and contaminants from the mating surface of the hub flange.
2. Use the J41013 to clean all rust and contaminants from the inside diameter of the hub section of the brake rotor to prevent any foreign material
from getting between the brake rotor and the hub flange.
3. Install the rotor by slowly fuming the rotor while pushing the rotor towards the axle.
4. Install the caliper and the bracket as an assembly to the vehicle.
5. Perform the following procedure before installing the caliper bracket mounting bolts.
^
Remove all traces of the original adhesive patch.
^
Clean the threads of the bolt with brake parts cleaner or the equivalent and allow to dry.
^
Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the threads of the bolt.
Notice: Refer to Fastener Notice in Service Precautions.
6. Install the caliper bracket mounting bolts.
^
For the 15 Series, tighten the brake caliper bracket mounting bolts to 175 Nm (129 ft. lbs.).
^
For the 25 series, tighten the brake caliper bracket mounting bolts to 300 Nm (221 ft. lbs.).
7. Install the tire and wheel assembly.
8. Lower the vehicle.
9. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
10. Slowly release the brake pedal.
11. Wait 15 seconds, then repeat steps 9-10 until a firm pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
12. Fill the master cylinder reservoir to the proper level with clean brake fluid.
