With Caliper On Vehicle

Fig 9 Caliper Assembly:

Check for piston seal leaks (evident by brake fluid in and around boot area and inboard lining) and for any ruptures of piston dust boot.
- If boot is damaged, or fluid is evident, it will be necessary to disassemble caliper assembly and install a new seal, boot, (and piston if damaged or corroded).

Check the mating surfaces of the abutments on the caliper and adaptor.
- If corroded or rusty, clean surfaces with wire brush. Inspect braking surfaces of disc.
