Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using a jack and jack stands.
Disconnect the battery for safety.

2. Inspect and Replace Brake Rotors

Remove Wheel:
- Use a socket set to remove the lug nuts and take off the wheel.
Inspect Rotors:
- Use a runout gauge to measure the rotor’s runout. If it exceeds manufacturer specifications, replace the rotors.
Remove Brake Caliper:
- Unbolt the caliper bracket using a socket set and lift the caliper off the rotor.
- Secure the caliper with a bungee cord to avoid stress on the brake line.
Remove Old Rotor:
- Unscrew the retaining screws (if applicable) and slide the rotor off the hub.
Install New Rotor:
- Clean the hub surface and install the new rotor, securing with screws.

3. Replace Brake Pads

Remove Old Brake Pads:
- Remove the caliper bracket by unbolting it, and slide out the old brake pads.
Install New Brake Pads:
- Apply brake grease to the back of the new pads and install them into the bracket.
Reassemble Caliper:
- Reattach the caliper bracket and caliper, ensuring all bolts are torqued to manufacturer specifications.

4. Inspect and Replace Suspension Components (if needed)

Check Control Arms and Bushings:
- Inspect for any signs of wear or damage. If components are worn, replace them.
Reassemble:
- Reinstall any removed components and ensure proper torque specifications are followed.

5. Final Steps

Reattach Wheel:
- Place the wheel back on and torque lug nuts to manufacturer specifications.
Reconnect Battery:
- Reconnect the battery and ensure all systems are operational.
