Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts on the wheel where the noise is occurring.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by fully detaching the lug nuts.

3. Inspect Brake Components

Brake Pads:
- Remove the brake caliper by unscrewing the caliper bolts.
- Slide the caliper off the rotor.
- Inspect the brake pads for thickness; if they are worn down to the metal, they need replacement.
Brake Rotors:
- Check the surface of the rotor for grooves or scoring. If damaged, consider resurfacing or replacing.
Brake Caliper:
- Inspect for proper movement and ensure the caliper slides are lubricated and not stuck.

4. Replace Components (if necessary)

Brake Pads:
- If worn, install new pads. Ensure they are oriented correctly.
Brake Rotors:
- If necessary, replace with new rotors. Ensure the mounting surface is cleaned before installation.
Caliper Reassembly:
- Reattach the caliper over the new pads and rotor.
- Torque caliper bolts to the manufacturer's specifications.

5. Reassemble and Test

Reinstall the wheel and tighten lug nuts to the specified torque.
Lower the vehicle and pump the brake pedal to reset the caliper position.
Test drive the vehicle at low speeds to ensure the grinding noise is resolved.
