Silverado Classic 2500 4WD V8-6.6L DSL Turbo (2007)
11. Remove the brake rotor.
12. If the rotor is difficult to remove due to corrosion in the hub area use the following procedure to remove the rotor.
1. Clean all the surface areas and the threaded holes of contamination.
2. Generously apply penetrating oil or the equivalent to the hub/rotor area.
3. Insert two M10 x 1.5 bolts or jack screws into the threaded holes of the rotor.
4. Tighten both bolts evenly to force the rotor from the hub.
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.
4. Important: If the rotor was removed using the jack screw method you must ensure that the hub flange is free of nicks or marks caused by this
procedure. Remove all raised nicks or marks before installing the rotor.
Align the rotor to its original position on the hub (if applicable) and install the rotor.
5. 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.
6. If the rotor assembled LRO measurement exceeds the specification, bring the LRO to within specifications. Refer to Brake Rotor Assembled
Lateral Runout Correction. See: Testing and Inspection/Brake Rotor Assembled Lateral Runout Correction
