Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen lug nuts.
Remove the wheel to access the braking components.

3. Inspect Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor.
Check the brake pads for uneven wear; replace if necessary.

4. Check Brake Rotors

Use a dial indicator to measure rotor runout.
If the rotor is warped (typically over 0.002 inches), resurface or replace it.

5. Reassemble Components

If pads and rotors are in good condition, reattach the caliper and torque bolts to manufacturer specifications (typically around 20-25 lb-ft).
Reinstall the wheel and torque lug nuts to manufacturer specifications (typically around 80-100 lb-ft).

6. Lower Vehicle and Test

Lower the vehicle and remove jack stands.
Perform a test drive to ensure the vibration is resolved.
