Disassembly (Except Justy)
- Thoroughly clean caliper assembly exterior with brake fluid. DO NOT use solvents, diesel fuel or gasoline as these chemicals break down reusable rubber components.
- If equipped, remove pad clip (shim) from piston opening. Remove piston dust boot retainer and dust boot. Place narrow wood block between piston and caliper body.
- With bleeder valve installed, apply low pressure compressed air to fluid inlet of caliper to force piston out of caliper bore. Remove piston boot and piston seal from caliper grooves. See Fig 1.
- Remove parking brake lever cap ring and rubber lever cap from rear of caliper. Remove snap ring from bottom of lever and spindle. Mount caliper assembly in soft-jawed vise. Install Puller (925471000) to push down on spring washer to release cone spring tension. See Fig 2.
- With spring tension released, pull out lever and spindle. Remove puller, and remove connecting link, return spring, spindle and cone spring.
NOTE:
When overhauling caliper, DO NOT remove mounting bracket. Loosen or remove mounting bracket only if mounting bracket is being replaced.
