Disassembly and Assembly

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:

^ Make sure all parts are clean before reassembly.
^ Use only new replacement parts.
^ Use only clean DOT 3 or DOT 4 brake fluid.
^ Do not allow dirt or other foreign matter to contaminate the brake fluid.
^ Do not mix different brands of brake fluid.
^ Avoid spilling brake fluid on painted. plastic or rubber surfaces as it can damage the finish; Wash spilled brake fluid off immediately with clean water.


1. Remove the banjo bolt and disconnect the brake hose from the caliper.

Caliper Assembly Removal:

2. Remove the caliper bolts, then remove the caliper.

Removing Pad Spring (Type B Only):

3. Remove the pad spring from the caliper body.

Removing Caliper Piston:

4. Place a wooden block or shop rag in the caliper opposite the piston, then carefully remove the piston from the caliper by applying air pressure through the brake line hole.

WARNING!
^ Do not place your fingers in front of the piston.
^ Do not use high air pressure; use an OSHA approved 30 PSI nozzle.
^ Cover the caliper with a shop towel to catch fluid spray.

Piston Seal And Boot:

5. Remove the piston boot and piston seal.


CAUTION:

^ Take care not to damage the cylinder.
^ Make sure all parts are clean before reassembly.
^ Use only new replacement parts.
^ Use only clean DOT 3 or DOT 4 brake fluid. ^ Do not allow dirt or other foreign matter to contaminate the brake fluid.
^ Do not mix different brands of brake fluid.
^ Avoid spilling brake fluid on painted, plastic or rubber surfaces as it can damage the finish.
^ Wash spilled brake fluid off immediately with clean water.
6. Clean the piston and caliper bore with brake fluid and inspect for wear or damage.

Applying Silicone Grease:

7. Apply silicone grease to a new piston seal, then in- stall the piston seal in the cylinder groove.
8. Apply rubber grease to a new piston boot, then in- stall the piston boot.
9. Lubricate the caliper cylinder and piston with brake fluid, then install the piston in the cylinder with the dished end facing in.

Installing Piston In Cylinder:

10. Reinstall the caliper in the reverse order of removal.

WARNING!
^ Always reinstall the brake pads in their original positions to prevent loss of braking efficiency.


11. Fill the brake reservoir up and bleed the brake system.
