  1. Install an open end wrench to hold the caliper guide pin in line with the brake caliper while removing or installing the caliper guide pin bolt. DO NOT allow the open end wrench to come in contact with the brake caliper. Allowing the open end wrench to come in contact with the brake caliper will cause a pulsation when the brakes are applied.
  2. If reusing the brake caliper guide pin bolt, prepare the guide pin bolt and the guide pin as follows:
    3. 2.1. Thoroughly clean the threadlocker residue from the guide pin bolt threads with denatured alcohol or equivalent and allow to dry.
    2.2. Thoroughly clean the threadlocker residue from the guide pin threads with denatured alcohol or equivalent and allow to dry.
  3. Apply high-temperature, high-strength threadlocker to 2/3 of the threaded length of the brake caliper guide pin bolt.

    4. Ensure there are no gaps in the threadlocker along the length of the filled area of the guide pin bolt.
