Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety goggles and gloves.

2. Lift 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 to ensure safety while working underneath.

3. Remove the Wheel

Using a socket set, loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect Brake Components

Brake Pads:
- Remove the brake caliper by unscrewing the caliper bolts.
- Inspect brake pads for wear. Replace if the friction material is less than 3mm thick.
Brake Rotors:
- Check the surface of the brake rotors for grooves or scoring. If damaged, replace the rotors.
- If the rotors are within spec, consider resurfacing them if necessary.

5. Reassemble and Test

Reinstall the brake caliper and secure it with the bolts, tightening to the manufacturer's torque specifications (typically around 20-30 ft-lbs).
Reattach the wheel and lug nuts, tightening them in a crisscross pattern to ensure even pressure.
Lower the vehicle back to the ground.

6. Final Checks

Pump the brakes a few times to ensure proper seating of the pads against the rotors.
Test drive the vehicle to confirm the grinding noise is resolved.
