Silverado Classic 1500 4WD V8-5.3L Hybrid (2007)
6. Compress the brake caliper pistons.
1. Install 2 large C-clamps over the top of the caliper housing and against the back of the outboard pad.
2. Slowly tighten the C-clamps until the pistons are pushed completely into the caliper bores.
3. Remove the C-clamps from the caliper.
7. Remove the brake caliper bracket bolts.
8. Notice: Refer to Brake Caliper Notice.
Remove the caliper and caliper bracket as an assembly. Support the caliper assembly with heavy mechanic's wire or equivalent. DO NOT
disconnect the hydraulic brake flexible hose from the caliper.
9. Remove the brake rotor retaining push nuts from the wheel studs, if necessary.
10. Remove the brake rotor screw.
11. 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.
12. Remove the rotor.
Installation Procedure
1. 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.
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.
