Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Inspect and Replace Brake Components

Remove Wheels
- Loosen lug nuts slightly while the vehicle is on the ground.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheels.
Inspect Brake Pads and Rotors
- Check the thickness of the brake pads; replace if below manufacturer's specifications (usually less than 3mm).
- Inspect the rotors for warping or scoring; if warped, replace rotors.
- Clean the rotor surface with brake cleaner if reusing.
Replace Brake Pads and Rotors
- If necessary, remove the caliper bolts and slide the caliper off the rotor.
- Replace the brake pads by sliding them out and installing new ones.
- Install new rotors if required, ensuring the correct orientation.
- Reinstall the caliper and torque bolts to manufacturer specifications.

3. Suspension Inspection and Repair

Check Control Arms and Bushings
- Visually inspect control arms and bushings for signs of wear or damage.
- Replace any worn or damaged components to restore proper alignment.
Alignment and Balancing
- After repairs, perform a wheel alignment to ensure proper tracking.
- Have the wheels balanced to eliminate vibration during driving.
