Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Rotors:
- Use a dial indicator to check for warpage. Replace if beyond manufacturer specifications (typically more than 0.002 inches).
Replace Brake Pads:
- If worn down to the manufacturer’s minimum thickness (usually 3mm), remove the caliper bolts and slide the caliper off.
- Replace the pads, ensuring to lubricate the backing plate with brake grease.
Reinstall Caliper:
- Reattach the caliper and torque the bolts to the manufacturer’s specification (typically 25-35 ft-lbs).

4. Wheel Alignment and Balancing

Check the wheel alignment using an alignment machine. Adjust as necessary to meet specifications.
Balance the tires if there is any uneven wear or if the vibration persists after brake work.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (usually 76-80 ft-lbs).
Perform a test drive to ensure the issue is resolved.
