Brake Caliper: Reassembly

Lubricate bore in caliper and new piston seal with clean brake fluid. Position seal in caliper bore groove. Lubricate piston with clean brake fluid, then assemble new boot into groove in piston, with fold facing open end of piston. Insert piston into caliper bore using care not to unseat seal. Do not force piston to bottom of bore. Position outer diameter of boot in caliper counterbore, then seat boot using suitable tool (J-26267) Starfire and Skyhawk or (J-22904) all other models. Check boot installation to make sure retaining ring moulded into boot is not bent and that boot is installed completely below caliper face. Install brake hose, using a new copper gasket.
