Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and securely lift the vehicle using a jack and jack stands.

2. Inspect Brake Pads

Remove the wheel to access the brake assembly.
Examine the brake pads for uneven wear or damage.
If worn unevenly, replace brake pads using the following sub-steps:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor.
- Remove the old brake pads and install new ones.

3. Check and Replace Brake Rotors

While the caliper is off, check the rotors for warping:
- Use a micrometer to measure rotor thickness at multiple points.
- If the rotor is warped (beyond manufacturer specs), proceed to replace it:
  - Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
  - Install new rotors, ensuring they are clean and free from oil.
  - Torque the retaining screws to the manufacturer’s specifications.

4. Inspect Calipers and Wheel Bearings

Check caliper operation by ensuring it moves freely:
- If it is sticking, clean and lubricate the caliper slides or replace the caliper if necessary.
Inspect wheel bearings for play:
- Wiggle the wheel to check for excessive movement; if present, replace the wheel bearing.

5. Reassemble and Test

Reinstall the caliper and wheel.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
Test drive the vehicle to confirm that vibrations have been resolved.
