Fig. 8 Installing boot to caliper:

1. Lubricate caliper piston bore and new piston seal with clean brake fluid. Position seal in bore groove.
2. Lubricate piston with clean brake fluid and assemble a new boot into the groove in the piston so the fold faces the open end of the piston, Fig. 7.
3. Using care not to unseat the seal, insert piston into bore and force the piston to the bottom of the bore.
4. Position dust boot in caliper counterbore and install, using suitable seal installer, Fig. 8. Check the boot installation to be sure the retaining ring molded into the boot is not bent and that the boot is installed below the caliper face and evenly all around. If the boot is not fully installed, dirt and moisture may enter the bore and cause corrosion.
5. Install the brake hose in the caliper using a new copper gasket.
6. Install shoes and re-install caliper assembly.
