Disassembly

WARNING:
- Never use an air hose or dry brush to clean brake assemblies.
- Use an OSHA-approved vacuum cleaner to avoid breathing brake dust.

CAUTION:
- Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid does contact the paint, wash it off immediately with water.
- To prevent spills, cover the hose joints with rags or shop towels.
- Clean all parts in brake fluid and air dry; blow out all passages with compressed air.





1. Remove the banjo bolt, and disconnect the brake hose from the caliper.
2. Remove the caliper bolts, then remove the caliper from the bracket.





3. Remove the pins and pin boots from the caliper bracket.

Removing Pad Spring:

4. Remove the pad spring from the caliper body.

Applying Compressed Air To Remove Piston:

5. If necessary, apply compressed air to the caliper fluid inlet to get the piston out. Place a shop rag or wooden block as shown to cushion the piston when it is expelled. Use low air pressure in short spurts.

WARNING:
- Do not place your fingers in front of the piston.
- Do not use high air pressure; use an OSHA approved 30 PSI nozzle.

6. Remove the piston from the caliper, and check the piston for scoring on surface.

Piston Components:

7. Remove the piston boot and piston seal.

CAUTION: Take care not to damage the cylinder bore.
