Brakes and Traction Control: Service Precautions

1. Grease or any other foreign material must be kept off lining surfaces and braking surfaces of disc brake rotor and external surfaces of wheel hub during service operation. In handling the disc brake rotor and disc brake caliper assemblies, avoid deformation of disc brake rotor and nicking or scratching of brake shoes and linings.
2. If a caliper piston is removed for any reason, the piston seals must be replaced. Exercise care not to damage the caliper piston by protecting it from contact with any metal or sharp objects.
3. During removal and installation of a wheel assembly, exercise care not to interfere with and damage front disc brake rotor shield or wheel cylinder bleeder screw fitting.
4. Front wheel bearing end play is critical and must be within specification (zero end play).
5. Do not attempt to clean or restore any oil or grease-soaked brake shoes and linings. When contaminated linings are found, brake shoes and linings must be replaced in complete axle sets and the rotor braking surfaces washed clean.
6. When replacing brake drum or rear disc brake rotor after either machining or new part replacement, make sure hub surface is clean and free of contaminants before installation.
7. Calipers must be installed with wheel cylinder bleeder screws in upward position for proper bleeding of air from brake system.
