Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery for safety.

2. Lift the Vehicle

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

3. Remove Wheel

Use a lug wrench to remove the wheel corresponding to the affected brake.
Place the wheel aside in a safe location.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check if the brake pads are worn down to the metal; if so, they need replacement.
Replace Brake Pads:
- Remove the caliper by unscrewing the caliper bolts with a socket set.
- Slide the caliper off the rotor and support it with a bungee cord to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.
- Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 20-25 lb-ft).

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- If rotors are scored or uneven, they may need resurfacing or replacement.
Replace Rotors:
- Remove the caliper bracket if necessary to access the rotor.
- Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
- Install the new rotor, securing it with retaining screws if applicable.

6. Reassemble and Reinstall Wheel

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer’s specifications (typically around 100-150 lb-ft).
