Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Use a jack to lift the vehicle and secure with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect Brake Components

Remove the brake caliper by loosening the mounting bolts.
Carefully slide the caliper off the brake rotor.
Inspect the brake pads for uneven wear and replace if necessary.
Check the brake rotor for warping or damage; replace if necessary.

4. Service Brake Calipers

Clean the caliper guide pins with brake cleaner and a rag.
Apply high-temperature grease to the guide pins to ensure proper movement.
Check for caliper piston operation; if it does not retract smoothly, consider rebuilding or replacing the caliper.

5. Replace Brake Pads

If uneven wear is found, replace both brake pads on the affected axle.
Ensure the new pads are compatible with the vehicle specifications.
Install the new brake pads, ensuring they are properly seated in the caliper bracket.

6. Reassemble and Test

Reinstall the brake caliper over the new pads and torque the bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a star pattern to the recommended torque (usually around 76 ft-lbs).
Lower the vehicle and pump the brake pedal to ensure proper pad seating.
