5. Piston seal from seal groove in caliper bore, using a small plastic or wood tool. Do not use a metal tool because this may damage caliper bore or seal groove. Inspect Caliper bore and seal groove for scoring, nicks, corrosion, and wear. Use crocus cloth to polish out light corrosion. Replace caliper housing if corrosion in and around the seal groove will not clean off with crocus cloth.
6. Bleeder valve cap.
7. Bleeder valve from caliper. Clean All parts in clean, denatured alcohol. Dry with unlubricated compressed air. Blow out all passages in caliper housing and bleeder valve.
