For 1990-2009 cars

Warning: Refer to Brake Dust Warning in the Preface section.

### Removal Procedure

1. Inspect the fluid level in the brake master cylinder reservoir.
2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, then no brake fluid needs to be removed from the reservoir before proceeding. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, then remove brake fluid to the midway point before proceeding.
3. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
4. Remove the tire and wheel. Refer to Tire and Wheel Removal and Installation.

Note: The upper caliper guide pin has a bushing as part of the pin guide. The lower caliper guide pin is of a solid design.

5. Remove the brake caliper.

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.

6. To loosen the brake caliper pin bolts, hold the brake caliper guide pin with a wrench.
7. Remove the brake caliper pin bolts.
8. Remove the brake caliper (1) from the mounting bracket.
9. Remove the brake pads from the disc brake caliper bracket.
10. Remove the brake pad retainers from the disc brake caliper bracket.
11. Remove the brake caliper guide pins (3) from the brake caliper mounting bracket (1).
12. Remove the caliper pin boots (2) from the brake caliper mounting bracket (1).

### Installation Procedure

Note:

• | Ensure that the caliper guide pin boots (2) are fully seated to the caliper guide pin retaining seat (3) of the caliper pin.

• | Ensure that the caliper guide pin boots (2) are fully seated to the caliper boot seal retaining seat (1) of the brake caliper mounting bracket.

1. Apply a thin coat of Niglube® SGM P/N 18046532 grease to the brake caliper guide pin boots.
2. Install the caliper guide pin boots (2) to the brake caliper mounting bracket retaining seat (1).
3. Install the break caliper guide pins (3) to the brake caliper mounting bracket (1).

Ensure the caliper guide pin retaining seat is fully seated to the caliper pin boot (2).

4. Carefully pull outward on the caliper guide pin (3) to ensure that the caliper guide pin retaining seat is fully seated to the caliper guide pin boot (2).
5. Install the brake pad retainers to the brake caliper bracket.
6. Install the brake pads to the brake caliper bracket.
7. Install the brake caliper to the caliper mounting bracket.

Note: If reusing the caliper pin bolts, the threads of the caliper pin bolts and the threads of the caliper bracket mounting holes must be free of residue and debris prior to application of threadlocker in order to ensure proper adhesion and fastener retention.

8. Prepare the bolts and the threaded holes for assembly:

8.1. | Thoroughly clean the residue from the bolt threads by using denatured alcohol or equivalent and allow to dry.

8.2. | Thoroughly clean the residue from the threaded holes by using denatured alcohol or equivalent and allow to dry.

8.3. | Apply threadlocker SGM P/N 89021297, or equivalent to 2/3 of the threaded length of the lower caliper pin bolt. Ensure that there are no gaps in the threadlocker along the length of the filled area of the bolt.

8.4. | Allow the threadlocker to cure approximately 10 minutes before installation.

8.5. | Apply a thin coat of high temperature silicone lube to the brake caliper guide pins.

Caution: Refer to Fastener Caution in the Preface section.

9. Install the brake caliper bolts (1).

Tighten
Tighten the brake caliper bolts to 34 N·m (25 lb ft).

10. Install the tire and wheel. Refer to Tire and Wheel Removal and Installation.
11. Lower the vehicle.
12. Fill the master cylinder to the proper level. Refer to Master Cylinder Reservoir Filling.
