Disassembly and Assembly

DISASSEMBLY
1. Remove caliper from vehicle.
2. Remove bleeder screw and drain remaining fluid from caliper. Install screw.





3. Remove dust boot retaining ring.
4. Position block of wood between piston and caliper, then apply compressed air to fluid inlet port and blow piston from caliper bore. Apply only enough pressure to ease piston out of bore.
5. Remove dust boot from piston, then use suitable wooden pick to carefully pry piston seal from caliper bore.
6. Remove bleeder screw, then the caliper bushings and bushing seals.
7. Wash all parts in denatured alcohol, then dry with compressed air.

INSPECTION
1. Inspect piston for scratches, scoring or damage. Replace if necessary.
2. Inspect caliper bore for scratches, scoring or corrosion. Light scratches or slight corrosion can be polished out using crocus cloth.
3. Ensure bleeder screw and bleeder screw bore hole in caliper are fully open.
4. Inspect caliper bushings for corrosion and dust boot retaining ring for damage or tension loss. Replace parts as necessary.

ASSEMBLY
1. Lubricate piston seal with suitable brake grease or clean brake fluid, then install into caliper bore.
2. Lubricate piston, then partially install into caliper bore. Ensure dust boot groove on piston remains above caliper bore.
3. Lubricate dust boot with suitable brake grease, then install onto piston.
4. Press piston fully inward until it bottoms in bore, then install dust boot retaining ring.
5. Install bleeder screw.
6. Install caliper bushings and new bushing seals. Lubricate inner surface of bushing seal and outer surface of bushings with suitable brake grease before installation.

CAUTION: Do not allow grease to enter piston bore.
