Cleaning and Inspection

1. Grease or any other foreign material must be kept off the brake lining surfaces of the rotor and external surfaces of the hub during service operations. In handling the rotor and caliper assemblies, avoid deformation of the brake rotor and nicking or scratching of brake lining.
2. If a caliper piston is removed for any reason, the piston seal must be replaced. Exercise care not to damage 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 the front disc brake rotor shields or the bleeder screw fitting.

CAUTION: Do not pry on caliper piston with a screwdriver or other tools as this will cause chipping.

4. To avoid bending or damaging the front disc brake rotor shield on full right or left wheel turns, the vehicle must be centered on the hoist before servicing any front end components.
5. Do not attempt to clean or restore any oil or grease-soaked brake linings. When contaminated linings are found, they must be replaced in complete axle sets.
6. Always replace rubber caliper pin insulators when replacing linings. Do not lubricate the disc brake caliper locating pins.
7. Disc brake caliper locating pin must be hand-started into front wheel spindle before tightening. This is to make sure the large diameter of pin is through outer holes to prevent binding or bending. Be careful not to damage the rubber caliper pin insulator when inserting the slide pins.
