Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, torque wrench, rotor runout gauge, OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel with a socket set.
- Check the thickness of the brake pads; replace if below manufacturer specifications (usually <3mm).
- Inspect rotors for grooves or scoring; replace if damaged.
Replace Brake Rotors if Necessary:
- Remove caliper and bracket using a socket set.
- Remove the rotor by unscrewing retaining screws if applicable.
- Install new rotor, ensuring it is seated correctly.
- Reattach caliper and bracket, tightening to manufacturer specifications.

3. Wheel Alignment and Balancing

Balance Wheels:
- Remove each wheel and take to a tire shop for balancing.
Check Alignment:
- Use an alignment machine to ensure the wheels are aligned to manufacturer specifications.
- Adjust as necessary.

4. Inspect Suspension Components

Check for Wear:
- Inspect control arms, tie rods, and bushings for play or wear.
- Replace any worn components following manufacturer specifications.
