Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Allow the vehicle to cool down.

2. Remove Wheel

Loosen the lug nuts on the front wheel using a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads and Rotors:
- Inspect the brake pads for uneven wear; replace if necessary.
- Check the brake rotors for warping or scoring. If warped (more than 0.002 inches), replace them.
Calipers:
- Ensure calipers are functioning properly and not sticking. Replace calipers if damaged.

4. Check Wheel Alignment and Tire Balance

If the inspection indicates misalignment, perform a wheel alignment procedure.
Check for tire balance; if unbalanced, re-balance the tires or replace if necessary.

5. Reassemble and Torque

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specifications (usually around 90-100 ft-lbs for most Volkswagen models).
