Solution

1. Preparation

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

2. Remove Wheel

Use a socket set to loosen lug nuts and remove the wheel.
Safety warning: Ensure the vehicle is securely lifted using a jack and jack stands.

3. Inspect Brake Components

Brake Rotors:
- Check for warping by using a dial indicator or visual inspection.
- If warped, proceed to replace rotors.
Brake Pads:
- Measure pad thickness; if below specifications, replace pads.
- Check for uneven wear; replace if necessary.

4. Replace Brake Rotors (if needed)

Remove caliper by unscrewing the caliper bolts with a socket set.
Hang the caliper using a bungee cord or rope to avoid straining the brake line.
Unscrew and remove the old rotor.
Install the new rotor, ensuring it is seated properly.
Reattach the caliper and torque bolts to the manufacturer's specifications (typically around 25 Nm).

5. Replace Brake Pads (if needed)

Compress the caliper piston using a brake caliper tool.
Remove old pads and install new pads, ensuring they are oriented correctly in the caliper bracket.
Reattach caliper and torque bolts to specifications.

6. Reinstall Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to specified values (usually 120 Nm).

7. Test Drive

Conduct a test drive to ensure the issue is resolved and brakes function smoothly.
