Brake Caliper: Service Precautions

Caution: Do not place your fingers in front of the piston in order to catch or protect the piston while applying compressed air. This could result in serious injury.

Notice: Use clean cloths to pad interior of caliper housing during piston removal. Use just enough air to ease the pistons out of the bores. If the pistons are blown out, even with the padding provided, it may be damaged.

Important: The caliper bracket bolts threads and the threaded holes of the caliper bracket must be free of threadlocker residue and debris prior to re-application of threadlocker in order to ensure proper adhesion and fastener retention.
^ Prepare the bolts and the threaded holes for assembly:
^ Thoroughly clean the residue from the fastener threads using denatured alcohol or equivalent and allow to dry.
^ Thoroughly clean the residue from the threaded holes using denatured alcohol or equivalent and allow to dry.
If reusing the old caliper bracket bolts, apply threadlocker GM P/N 12345493, (Canadian P/N 10953488), or equivalent to two-thirds of the threaded length of the fastener. Ensure that there are no gaps in the threadlocker along the length of the filled area of the fastener. Allow the threadlocker to cure approximately ten minutes before installation.
