Some General Motors SUY owners may complain of a rattle noise coming from the front of the vehicle while driving at slow speeds over rough road surfaces - when the brake pedal is not applied. This condition may be caused by the interface of the front brake caliper guide pins and the front brake caliper bracket.
To isolate the brake caliper guide pins as a potential source of the noise, apply the brakes when the noise is apparent. If the noise stops when the brakes are applied and returns once released, then the caliper guide pin bushings are the most likely source of the concern.

|1. Raise and support the vehicle.
2. Remove the wheel assembly.
3. Install and firmly hand tighten two wheel nuts to opposite wheel studs in order to retain the rotor
to the hub.
4. Install a large C-clamp over the body of the brake caliper with the C-clamp ends against the rear of
the caliper body and against the outboard brake pad.
5. Tighten the C-clamp evenly until the caliper piston is compressed into the caliper bore enough to
allow the caliper to slide past the brake rotor.
6. Remove the C-clamp from the caliper.
7. Remove the brake caliper lower guide pin bolt (Figure 1).
Note: Support the brake caliper with heavy mechanic's wire, or equivalent.
8. Without disconnecting the hydraulic brake flexible hose, pivot the caliper upward and secure the caliper with heavy mechanic's wire, or equivalent (Figure 2).
9. Remove the lower caliper pin taking care not to damage the pin boot (Figure 3).
10. Remove the rubber bushing from the caliper pin (Figure 4).
11. Clean the pin and install a new bushing.
12. Lubricate the caliper pin and bushing assembly with a light coat of high temperature silicone brake lubricant and install in the caliper bracket.
13. Remove the support and rotate the brake caliper into position over the disc brake pads and to the caliper mounting bracket.
14. Repeat Steps 1-13 on opposite side brake assembly.
|Note: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants or corrosion inhibitors' on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
1. Install the lower brake caliper guide pin bolt. Tighten the bolt to 32 lb ft (44 N.m)
2. Remove the wheel nuts.
3. Install the wheel assembly.
4. Repeat Steps 1-3 on opposite side brake assembly.
5. Lower the vehicle.
6. With the engine OFF, gradually apply the brake pedal approximately 2/3 of its travel distance.
7. Slowly release the brake pedal.
8. Wait 15 seconds, then gradually apply the brake pedal approximately 2/3 of its travel distance
again until a firm brake pedal apply is obtained. This will seat the brake caliper pistons and
9. Drive the vehicle to confirm the noise is gone.
