Avalanche 1500 4WD V8-53L (2007) Disc Brake System Rotor Service
10. Remove the brake rotor retaining push nuts from the wheel studs, if necessary.
11. Remove the brake rotor screw.
Important: Perform the following service procedures to separate the brake rotor from the wheel hub.
12. Install the wheel nuts on the wheel studs.
13. Using a deadblow hammer, strike the rotor between the wheel studs to separate the rotor from the wheel hub.
14. Remove the wheel nuts.
15. Remove the rotor.
16. If the brake rotor does not separate from the wheel hub, perform the following steps.
^
Clean all the surface areas and the threaded holes of contamination.
^
Generously apply penetrating oil or equivalent to the hub/rotor area.
^
Insert 2 M10 x 1.5 bolts into the threaded holes of the rotor.
^
Tighten the bolts evenly to force the rotor from the hub.
Installation Procedure
Notice: Any new rotor must have the protective coating removed from the friction surfaces before being placed in service. Remove the protective
coating using denatured alcohol or an equivalent, and wipe the surface clean with clean cloths. Do not use gasoline, kerosene, or other oil base
solvents which may leave an oily residue. This residue is damaging to the brake lining and is flammable.
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. Using the J 42450-A, clean all rust and contaminants from the mating surface of the hub flange.
2. Using the J 41013, 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.
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.
