Brake Caliper: Testing and Inspection

NOTE: When raising the vehicle make sure that the hoist lift points do not rest on the caliper pins.

1. Raise vehicle on hoist.
2. Remove the wheel and tire from the front disc brake hub and rotor (1102).
3. Visually check the disc brake caliper (2B120). If the disc brake caliper housing is leaking, it should be replaced. If a caliper piston (2196) is leaking, the caliper disc brake caliper must be disassembled and new caliper piston installed. If a caliper piston is seized in the bore, a new disc brake caliper housing is required.

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

4. If a disc brake caliper caliper piston is removed for any reason, the piston seal must be replaced. Exercise care not to damage plastic caliper piston by protecting it from contact with any metal or sharp objects.
5. Clean all metal parts with isopropyl alcohol. Then, clean out and dry the grooves and passageways with compressed air. Make sure that caliper bore and component parts are thoroughly clean and dry prior to assembly.
6. Check the cylinder bore and caliper piston for excessive scoring or corrosion.
