Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Brake Rotor Inspection and Replacement

Remove Wheel
- Use a lug wrench to loosen and remove the wheel bolts.
- Remove the wheel and set it aside.
Inspect Brake Rotors
- Remove the caliper by loosening the caliper bolts with a socket set.
- Slide the caliper off the rotor and secure it with a bungee cord to avoid stress on the brake line.
- Measure the rotor thickness with a micrometer. If warped or below minimum thickness, replace the rotor.
Replace Rotors
- If necessary, unbolt the rotor from the hub using the appropriate socket.
- Install the new rotor, ensuring it is securely fastened.
- Reinstall the caliper over the new rotor and tighten caliper bolts to manufacturer specifications (typically 25-30 lb-ft).

3. Brake Pad Inspection and Replacement

Check Brake Pads
- Inspect the brake pads for wear. Minimum thickness should be above 3mm.
- If worn unevenly, replace both pads on the affected axle.
Replace Brake Pads
- Remove old pads from the caliper bracket.
- Clean the caliper bracket and install new pads, ensuring proper orientation.
- Use brake grease on the pad backing to reduce noise.

4. Suspension Component Inspection

Examine Suspension
- Visually inspect control arms, bushings, and struts for any signs of wear or damage.
- Replace any damaged components as necessary.

5. Wheel Alignment and Balancing

Perform Wheel Alignment
- Take the vehicle to a shop equipped with alignment tools.
- Adjust alignment settings to meet manufacturer specifications.
