Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Lift the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the brake components.

3. Inspect Brake Components

Rotors: Remove the brake caliper (if necessary) and inspect the rotor for warping. If warped, replace with new rotors.
- Tools: Caliper tool, socket set.
- Warning: Support the caliper to avoid damaging the brake line.
Brake Pads: Check the thickness and condition of the brake pads. Replace if worn below manufacturer specifications.
- Tools: Torque wrench (for caliper bolts), brake grease for installation.

4. Replace Components (if needed)

If rotors or pads are worn, replace them:
- Rotors: Install new rotors and torque to manufacturer specifications.
- Brake Pads: Install new pads and apply brake grease to the backing to reduce noise.

5. Reassemble and Test

Reinstall the wheel and torque lug nuts to specification.
Reconnect the negative battery terminal.
Lower the vehicle and perform a test drive to ensure the issue is resolved.
