Removal

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.

DO NOT use any air tools to remove or install the 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 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.

1.	Raise and support the vehicle.

2.	Remove the tire and wheel assembly.

3.	Remove the brake caliper guide pin bolts (1). Hold the brake caliper guide pins stationary when removing the guide pin bolts, Fig. 1.

4.	Without disconnecting the brake caliper hose, remove the brake caliper and support with heavy mechanics wire or equivalent.

5.	Remove the inner brake pad (1). Note the location of the wear sensor for correct installation, Fig. 2.

6.	Remove the outer brake pad (2), Fig. 2.

7.	Remove the brake pad shims (1), Fig. 3.

8.	Remove the brake caliper bracket bolts (1), Fig. 4.

9.	Remove the brake caliper bracket (1), Fig. 5.

Installation

If reusing the caliper bracket bolts the threads of the caliper bracket 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.

DO NOT use any air tools to remove or install the guide pin bolts. Use hand tools ONLY.

1.	Install the brake caliper bracket.

2.	Prepare the bolts and the threaded holes for assembly, noting following:

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 with denatured alcohol or equivalent and allow to dry.

Apply threadlocker GM part No. 12345493, or equivalent to 2/3 of the threaded length of the lower caliper bracket bolts.

Ensure there are no gaps in the threadlocker along the length of the filled area of the bolts.

Allow the threadlocker to cure approximately 10 minutes before installation.

3.	Install the brake caliper bracket bolts and torque to 89 ft. lbs.

4.	Install the brake pad shims.

5.	Install the inner brake pad. Note the location of the wear sensor for correct installation.

6.	Install the outer brake pad.

7.	Position the brake caliper to the bracket.

8.	Holding the brake caliper guide pins stationary, install the brake caliper guide pin bolts and torque to 20 ft. lbs.

9.	Install the tire and wheel assembly.

10.	Lower the vehicle.
