Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, run-out gauge, caliper tool, brake cleaner, safety glasses, gloves.
Raise the vehicle and securely support it on jack stands.

2. Remove Wheel

Loosen lug nuts with a lug wrench before lifting the vehicle.
Remove the wheel by unscrewing the lug nuts completely.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Use a run-out gauge to measure rotor thickness and warping.
- If warped beyond specifications (usually 0.002 inches), replace the rotors.
Inspect Brake Pads:
- Check for wear indicators; if pads are worn down below 3mm, replace them.
- Ensure pads are properly seated in the calipers.

4. Reassemble

Reinstall new rotors and brake pads, ensuring all components are clean and free of debris.
Torque the lug nuts to the manufacturer’s specifications (typically around 80-90 ft-lbs for most vehicles).
Reattach the wheel and lower the vehicle.

5. Test Drive

After completing the repair, perform a test drive to ensure the braking system is functioning properly and monitor for any vibrations or noises.
