Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Remove the caliper bolts with a socket set and lift the caliper away from the rotor.
3. Inspect the brake pads for wear; if less than 3mm thick, replace them.
4. Install new brake pads in the caliper bracket and ensure they fit snugly.
5. Reattach the caliper and tighten bolts to the manufacturer's torque specifications.

3. Inspect and Replace Rotors (if necessary)

Sub-steps:
1. If rotors are below the minimum thickness or warped, remove them by unscrewing the retaining screws.
2. Clean the hub surface with a wire brush to ensure proper rotor seating.
3. Install the new rotor and secure it with retaining screws.
4. Repeat the installation process for each wheel as needed.

4. Check and Adjust Suspension Components

Sub-steps:
1. Inspect control arms, bushings, and tie rods for signs of wear or damage.
2. Replace any worn components.
3. Perform a wheel alignment if any suspension parts were replaced.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and tighten lug nuts to the specified torque.
2. Reconnect the battery.
3. Lower the vehicle and perform a test drive to ensure the issue is resolved.
