Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Using a hydraulic jack, lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Pads and Rotors

Inspect: Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Replace:
- If brake pads are worn down (less than 3mm), replace them.
- Check rotors for warping using a dial indicator or by feel. If warped (greater than 0.002 inches), replace the rotors.
Install New Parts: Position the new pads and rotors, ensuring they are properly seated.
Torque Specifications: Reinstall caliper bolts to manufacturer specifications (usually around 30 Nm, but confirm with a repair manual).

4. Align and Balance the Wheels

Alignment: Use an alignment machine to check and correct wheel alignment according to manufacturer specifications.
Balancing: Mount the front wheels on a tire balancer and adjust weights as necessary to ensure proper balance.

5. Inspect Suspension Components

Check all suspension components (control arms, ball joints, tie rods) for wear or damage.
Replace any worn or damaged parts as necessary.

6. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (typically around 110 Nm).
