Disassembly Procedure
1. Drain all the brake fluid from the caliper.
2. Pad the interior of the caliper with clean shop towels.
Caution: Do not place your fingers in front of the piston in order to catch or protect the piston while applying compressed air. This could
result in serious injury.
Notice: Use just enough air pressure to ease the piston out of the bore. You can damage a blown-out piston even with the padding.
3. Remove the pistons (2) from the caliper bores.
4. Remove the boots (1) from the caliper bores. Do not scratch the caliper bores.
5. Remove the piston seals (3) from the caliper bores. Do not use a metal tool.
6. Remove the bleeder valve cap (4).
7. Remove the bleeder valve (5) from the caliper housing (6).
8. Clean the bleeder valve, the caliper bores, the caliper passages and the pistons with denatured alcohol. Dry the parts and blow out the brake fluid
passages. Use dry and filtered compressed air.
9. Replace the pistons or the caliper if any of the following conditions exist:
^
Scoring on the piston surface or in the caliper bore
^
Corrosion on the piston
^
Chrome plating damage on the piston
^
Corrosion in the caliper bore
Use a crocus cloth in order to polish light corrosion from the caliper bore. Replace the caliper if the corrosion cannot be removed.
