Solution

1. Preparation

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

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Visually check for warping or significant wear.
- Measure rotor thickness with a micrometer to ensure it meets specifications.
Replace Rotors:
- Remove caliper bolts and slide the caliper off the rotor.
- Unbolt the rotor from the hub and replace it with a new rotor.
- Torque the rotor bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

Inspect Pads:
- Check the thickness of the brake pads; if they are below the manufacturer's minimum thickness, replace them.
Replace Pads:
- Remove the caliper bracket bolts and the caliper bracket.
- Replace old pads with new ones, ensuring they are properly seated.
- Apply brake grease to the pad backing to reduce noise.

5. Inspect and Repair Suspension Components

Check Components:
- Inspect struts, control arms, and bushings for any signs of wear or damage.
Replace Parts:
- If any components are worn, use appropriate tools to remove and replace them, following manufacturer specifications.

6. Reassemble and Lower Vehicle

Reinstall the caliper bracket and caliper.
Replace the wheels and lower the vehicle.
Torque wheel nuts to the manufacturer's specifications.
