Solution

1. Preparation

Gather tools such as a jack, jack stands, lug wrench, torque wrench, and brake cleaner.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery if working on electronic components.

2. Remove Wheel Assembly

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check the thickness of each brake pad.
- If worn unevenly, replace all pads on the affected axle.
Inspect Brake Calipers:
- Ensure calipers slide freely and are not sticking.
- If defective, replace the caliper and bleed the brake lines afterward.
Inspect Rotors:
- Check for warping or grooves; replace if necessary.
- Resurface rotors if they are within specifications.

4. Reassemble and Adjust

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).
Reconnect the battery if it was disconnected.
