Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on where the noise is originating.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Inspect the wheel for any debris that may affect braking.

4. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a ratchet and socket.
- Take off the caliper and check the brake pads for thickness and wear. Replace if less than 3mm.
Brake Rotors:
- Check the surface of the rotors for scoring or excessive wear. If damaged, replace or resurface as needed.
Caliper:
- Ensure the caliper is not sticking. If it is, it may need to be cleaned or replaced.

5. Reassemble Components

Reinstall the caliper and secure it with the caliper bolts. Torque to manufacturer specifications (typically around 25-30 ft-lbs).
Place the wheel back on and hand-tighten the lug nuts.

6. Lower the Vehicle

Remove the jack stands and carefully lower the vehicle back to the ground.

7. Final Check

Reconnect the battery.
Press the brake pedal a few times to seat the brake pads against the rotors.
