Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Check for uneven wear or thickness below manufacturer specifications.
- Replace if necessary.
Brake Rotors:
- Measure thickness and check for warping using a dial indicator.
- Resurface or replace if warped or below minimum thickness.

4. Reassemble Components

Install new or resurfaced brake rotors onto the hub.
Replace brake pads, ensuring proper orientation and alignment.
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Torque Lug Nuts

Carefully lower the vehicle from jack stands.
Torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs depending on model).

6. Test Drive

Conduct a test drive to ensure no vibrations occur during braking.
Monitor braking performance and listen for any abnormal noises.
