Brakes and Traction Control: Service Precautions

1. Grease or any other foreign material must be kept off the lining surfaces of the disc brake rotor and external surfaces of the wheel hub during service operations. In handling the disc brake rotor and disc brake caliper, avoid deformation of the disc brake rotor and nicking or scratching of brake pads and linings.
2. If a caliper piston is removed for any reason, the piston seal must be replaced.
3. During removal and installation of a wheel assembly, exercise care not to interfere with the front disc brake rotor shield or the wheel cylinder bleeder screw.
4. Front wheel bearing end play is critical and must be within specification.
5. To avoid bending or damaging the front disc brake rotor shield on full RH or LH wheel turns, the vehicle must be centered on the hoist before servicing any front end components.
6. Do not attempt to clean or restore any oil or grease-soaked brake pads and linings. When contaminated linings are found, they must be replaced in complete axle sets.
7. When replacing disc brake rotor after either machining or new part replacement, make sure hub surface is clean and free of contaminants before installation.
