Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during brake system inspection.

2. Inspect and Replace Brake Components

Remove Wheel
- Loosen lug nuts slightly while the vehicle is on the ground.
- Raise the vehicle with a jack and secure it with jack stands.
- Remove the lug nuts and wheel.
Inspect Brake Pads and Rotors
- Check the thickness of the brake pads; replace if they are worn down (less than 3mm).
- Inspect the rotors for warping or scoring. If warped, they should be resurfaced or replaced.
Replace Brake Pads and Rotors (if necessary)
- Remove the caliper by unbolting it from the bracket.
- Replace the old pads with new ones, ensuring proper orientation.
- If rotors are replaced, remove the old rotor and install the new one securely.

3. Check and Adjust Wheel Alignment and Balance

Check Wheel Alignment
- Use alignment equipment to assess if the wheels are aligned according to manufacturer specifications.
- Adjust as necessary to ensure proper alignment.
Balance the Wheels
- Mount the wheel onto a tire balancing machine to check for imbalance.
- Add weights as required to achieve proper balance.

4. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the manufacturer's torque specifications.
Reconnect the battery.
Take the vehicle for a test drive to ensure the issue is resolved.
