Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure all tires have sufficient clearance for inspection.

3. Inspect Brake Components

Brake Pads:
- Remove the wheel by loosening the lug nuts and taking off the tire.
- Inspect brake pads for thickness; replace if worn below 3mm.
Brake Rotors:
- Check rotors for signs of warping using a runout gauge; replace if out of specification.
- Clean the rotor surface with brake cleaner and a lint-free cloth.

4. Check Suspension Components

Inspect control arms, ball joints, and tie rods for wear or damage.
Replace any worn suspension parts as necessary.

5. Reassemble and Lower Vehicle

Reinstall the wheel and tighten lug nuts to the manufacturer’s torque specification.
Lower the vehicle from the jack stands and remove the jack.
