WARNING: Refer to Brake Dust Warning . CAUTION: 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. 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 Guide Pin Bolt (Qty: 2) CAUTION: Refer to Fastener Caution . Procedure DO NOT use any air tools to remove or install the brake caliper guide pin bolts. Use hand tools ONLY. 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 bolts. DO NOT allow the open end wrench to contact the brake caliper. Allowing the open end wrench to contact the brake caliper will cause a pulsation when the brakes are applied. Ensure the brake caliper guide pin seals are fully seated in the groove of the brake caliper guide pins and the guide pins slide freely in the caliper bracket bores. Tighten: 100 N.m (74 lb ft)
