Brake Caliper: Assembly

Assemble seal in piston groove closest to flat end of piston. Lip on seal must face toward large end of piston. Seal lips must be in piston groove, not extending over step in end of groove. Place spring in bore. Lubricate seal with clean brake fluid. Install piston assembly in bore, using suitable compressor tool (J-22629 or J-22639). Place boot in piston groove closest to concave end of piston. Position suitable boot seal installer tool (J-22628 or J-22639) over piston and seat steel boot-retaining ring evenly in counterbore, below machined surface of caliper. Install "O" rings in fluid transfer holes. Lubricate, attach, and torque caliper halves together.
