Solution

1. Preparation

Tools Required: Safety goggles, gloves, jack and jack stands, wheel chocks, OBD-II scanner, torque wrench.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Brake Pads

Remove the wheel using a torque wrench to loosen the lug nuts.
Inspect the brake pads for uneven wear; replace if thickness is below manufacturer specifications.
- Sub-steps:
  - Remove the caliper bolts and lift the caliper away.
  - Remove old brake pads and compare with new ones.
  - Install new brake pads ensuring they are seated properly.
Reattach the caliper and torque to manufacturer specifications.

3. Check and Resurface/Replace Brake Rotors

Inspect rotors for warping or scoring.
- Sub-steps:
  - Use a dial indicator to measure rotor runout.
  - If warped, either resurface the rotors or replace them if they are below minimum thickness.
Install rotors and torque to manufacturer specifications.

4. Wheel Alignment and Balancing

After reassembly, check wheel alignment using a professional alignment tool.
- Sub-steps:
  - Adjust toe, camber, and caster settings as needed to specifications.
Balance the tires if there is any noticeable vibration during test driving.

5. Reconnect Battery and Test Drive

Reconnect the battery and ensure all tools and equipment are removed from the vehicle.
Conduct a test drive to verify that the issue has been resolved.
