Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel Assembly

Loosen the lug nuts on the wheel associated with the grinding noise.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and support it with a bungee cord or similar tool (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Inspect the brake pad thickness; replace if below manufacturer specifications (usually less than 3mm).
- Install new brake pads, ensuring they are properly seated.
Brake Rotors:
- Inspect the rotor surface for grooves or damage.
- If damaged, remove the rotor by unscrewing the retaining screws or tapping it gently with a hammer.
- Install new rotors, ensuring they are clean and free of grease.
- Torque the rotor retaining screws to manufacturer specifications.

4. Reassemble Brake Assembly

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Test Brakes

Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts in a star pattern to ensure even pressure.
Pump the brake pedal a few times to seat the pads against the rotors.
Test drive the vehicle to ensure the grinding noise is eliminated and brakes function properly.
