9. Install the new dust boot seal onto the caliper piston (2).
10. Insert the caliper piston into the caliper bore; using a spanner type wrench, rotate the piston (2) clockwise to fully seat the piston into the caliper
body (1).
11. Fully seat the piston dust boot seal in the seal counterbore.
12. Install the piston dust boot seal retaining ring to the groove in the caliper seal counterbore.
13. Install the brake caliper to the vehicle.
Inspect the brake caliper for brake fluid leaks while performing the hydraulic brake system bleeding procedure after the caliper has been installed
to the vehicle. If the brake caliper leaks brake fluid from the FRONT of the caliper past the piston dust boot seal, replace the caliper piston
assembly. The piston integral adjustment mechanism contains a non-serviceable seal which may be allowing brake fluid to leak past it through a
bleed hole near the end of the caliper piston.
