Caliper Disassembly
1. Remove both brake pads from the caliper (see “FRONT
BRAKE PADS - Pad Removal”).
2. Remove mount bracket assembly and dust boots.
3. Thoroughly clean the caliper before disassembly and
prepare a clean work area for disassembly.
4. Use a commercially available caliper piston pliers to extract
the pistons from the caliper.
IMPORTANT: Do not remove the caliper pistons with
a standard pliers. The piston sealing surfaces will
become damaged if a standard pliers is used.
5. Once the pistons are removed, use a pick to carefully
remove the square O-rings from the caliper. O-rings should
be replaced during caliper service.
6. Clean the caliper body, piston, and retaining bracket with
brake cleaner or alcohol.

body.
