Tahoe 2WD V8-5.3L (2007)
10. Remove the caliper and caliper bracket as an assembly and support with heavy mechanics wire or equivalent. DO NOT disconnect the hydraulic
brake flexible hose from the caliper.
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
Important: 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 to clean all rust and contaminants from the mating surface of the hub flange.
2. Use the J 41013 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. If the rotor was removed and installed as part of a brake system repair, measure the assembled lateral runout (LRO) of the rotor to ensure optimum
performance of the disc brakes. Refer to Brake Rotor Assembled Lateral Runout Measurement.
7. If the rotor assembled LRO measurement exceeds the specification, bring the LRO to within specifications. Refer to Brake Rotor Assembled
Lateral Runout Correction.
8. Install the caliper and caliper bracket as an assembly.
9. 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.
