    IMPORTANT: If reusing the brake caliper bolts the threads of the bolts and the threads of the knuckle mounting holes must be free of residue and debris prior to application of threadlocker in order to ensure proper adhesion and fastener retention.
  1. Prepare the bolts and the threaded holes for assembly:
    • Thoroughly clean the residue from the bolt threads by using denatured alcohol or equivalent and allow to dry.
    • Thoroughly clean the residue from the threaded holes by using denatured alcohol or equivalent and allow to dry.
  2. Apply threadlocker GM P/N 12345493 (Canadian P/N 10953488), or equivalent to 2/3 of the threaded length of the caliper bolts. Ensure that there are no gaps in the threadlocker along the length of the filled area of the bolts.
  3. Allow the threadlocker to cure approximately 10 minutes before installation.
  4. NOTE: Refer to Fastener Notice .
  5. Install the brake caliper bolts (1).
