DISASSEMBLE
1. Remove caliper assembly as described under Brake Shoe & Lining, Replace.
2. With brake hose attached to caliper. carefully depress brake pedal to push piston out of caliper bore. Prop brake pedal to any position below first inch of brake pedal travel to prevent brake fluid loss.
3. If pistons are to be removed from both calipers, disconnect brake hose at frame bracket after removing piston, then cap brake line and repeat procedure to remove piston from other caliper.
4. Disconnect brake hose from caliper.
5. Mount caliper in a soft jawed vise.
6. Support caliper and remove dust boot and discard.
7. Using a small wooden or plastic stick, remove seal from groove in piston bore and discard.

ASSEMBLE
1. Mount caliper in a soft jawed vise.
2. Lubricate piston seal with clean brake fluid and install seal in caliper bore groove. Ensure seal is properly seated.
3. Lubricate piston boot with clean brake fluid and install boot in caliper bore groove.
4. Using a hammer and small steel plate or a suitable C-clamp, drive into caliper until seated. Ensure boot is properly seated in caliper bore.

6. Spread boot with finger and work piston into boot, then press down on piston.
7. Remove plug and carefully push piston down in bore until bottomed.
8. Compress flanges of guide pin bushings and install bushings on caliper housing. Ensure that bushing flanges extend evenly over caliper housing on both sides. On all front wheel drive except 1982---84 Omni and Horizon and 1983---84 Charger and Turismo, remove Teflon sleeves from guide pin bushings prior to installing bushings into caliper. After bushings are installed into caliper, reinstall Teflon sleeves into bushings.
9. Connect brake hose to brake line at frame bracket.
10. Install caliper on vehicle as described under Brake Shoe & Lining, Replace.
