    CAUTION:
    • If the double-sided adhesive tape affixed to the shim contacts the caliper and piston, the tape's adhesive surface will roughen causing disc pad wear which may become a source of noise when the mounting support moves. When moving the mounting support be careful not to allow the double-sided adhesive tape on the shim to contact the caliper and piston.
  18. Temporarily install the caliper installation bolt.
