DISASSEMBLE
1. Remove caliper assembly, then drain brake fluid from caliper.
2. Remove cylinder boot set ring and boot from cylinder groove, Fig. 1.
3. Use clean shop towels to pad interior of caliper assembly, then remove piston by directing compressed air into caliper brake hose inlet hole. Use just enough air pressure to ease piston out of bore. Do not place fingers in front of piston for any reason when applying compressed air. This could result in serious personal injury.
4. Using a small piece of wood or plastic, remove piston seal from bore. Do not use a metal tool of any kind to remove seal as it may damage bore.
5. Remove bleeder valve.
6. Inspect piston for scoring, nicks, corrosion, and wear and replace as needed.
7. Inspect caliper housing and seal groove for corrosion, nicks, scoring and excessive wear, and use crocus cloth to polish away corrosion from housing bore. Replace caliper housing if corrosion in and around seal groove will not clean up with crocus cloth.
8. Clean all parts with denatured alcohol. Dry with unlubricated compressed air. Blow out all passages in housing and bleeder valve.

ASSEMBLE
1. Apply suitable grease to piston seal and cylinder wall, then install seal. Check to ensure piston seal is not twisted.
2. Install new boot on piston so side with 2 grooves faces in toward cylinder and side with 3 grooves faces out, Fig. 5.
3. Install piston in caliper so it projects about .4 inch to ease installation of boot on caliper housing. Install boot on caliper housing, then install set ring.
4. Install bleeder valve.
5. Check that caliper slide bushings are lubricated with rubber grease. Check that slide bushing in each carrier hole can be moved smoothly in each direction.
6. Install caliper and inside pad on knuckle.
7. Tighten caliper bolts to specifications.
8. Connect brake hose, then bleed hydraulic system.
9. Install wheel.
10. Lower vehicle and test brakes. Before moving vehicle, pump brake pedal several times to be sure it is firm. Do not move vehicle until a firm pedal is obtained.
