Solution

1. Preparation

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

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the 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 take off the wheel.

3. Inspect and Remove Brake Components

Inspect brake rotors for warping using a dial indicator.
If rotors are warped, remove caliper bolts using a socket wrench.
- Sub-steps:
  1. Support the caliper with a bungee cord to avoid strain on the brake line.
  2. Remove the caliper from the rotor.
Remove brake pads and inspect for wear. Replace if necessary.

4. Replace or Resurface Rotors

If rotors are warped:
- Option 1: Replace rotors with new ones.
- Option 2: Resurface rotors if they are within specifications.
Follow manufacturer torque specifications for rotor installation (usually around 80-100 ft-lbs depending on the model).

5. Reassemble Brake Components

Reinstall the brake pads and caliper.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to ensure even pressure.

6. Test Drive

Take the vehicle for a test drive to ensure vibrations have been resolved.
Monitor brake performance and listen for abnormal noises.
