2
Check brake rotors for warping or uneven surfaces.
3
Examine suspension components, including control arms and bushings, for damage or wear.
4
Inspect wheel alignment and balance.
5

Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Gather tools and safety equipment: gloves, safety glasses, jack, jack stands, lug wrench, torque wrench, and an OBD-II scanner.

2. Remove the Wheel

Loosen the lug nuts while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Inspect the brake pads for thickness; replace if worn down to the minimum thickness (usually around 3mm).
- Remove the caliper bolts and slide the caliper off the rotor, using a caliper hanger to support it.
- Replace the brake pads, ensuring they are installed correctly.
Brake Rotors:
- Check the rotors for warping by measuring with a dial indicator; replace if warped beyond specification (usually more than 0.003 inches).
- If resurfacing is recommended, follow manufacturer specifications for thickness and finish.

4. Inspect Suspension and Steering Components

Check control arms, ball joints, and bushings for signs of wear or damage.
Tighten any loose components to manufacturer specifications.
Replace any damaged or worn suspension components.

5. Reassemble and Torque

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Use a torque wrench to tighten the lug nuts to the manufacturer-recommended torque specification (usually around 80-100 ft-lbs for the Golf).
