Callout	Component Name
CAUTION: Refer to Brake Dust Caution . NOTE: Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak. NOTE: Any new rotor must have the protective coating removed from the friction surfaces before being placed in service. Remove the protective coating using denatured alcohol or an equivalent brake cleaner, and wipe the surface clean with clean cloths. Do not use gasoline, kerosene, or other oil base solvents which may leave an oily residue. This residue is damaging to the brake lining and is flammable. Preliminary Procedures Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle . Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation .
1	Brake Caliper Bracket Bolt (Qty: 2) NOTE: Refer to Fastener Notice . Procedure Remove all traces of the adhesive patch on the brake caliper bracket bolts and threaded holes of the brake caliper bracket. Clean the brake caliper bracket bolt threads and the threaded holes of the brake caliper bracket with denatured alcohol or equivalent and allow to dry. Apply threadlocker G/M P/N 12345493 (Canadian P/N 10953488) to 2/3 of the threaded portion of the brake caliper bolts. Tighten: 175 N.m (129 lb ft)
