Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gear, including gloves and safety glasses.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts of the wheel where the grinding noise is present.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; they should be at least 3mm thick.
- Look for uneven wear patterns or cracks.
Replace Brake Pads:
- Remove the caliper bolts using a socket or wrench.
- Carefully slide the caliper off the rotor, supporting it with a bungee cord or hanging it without stress on the brake line.
- Remove the old pads from the caliper bracket.
- Install new brake pads into the caliper bracket, ensuring they are positioned correctly.

4. Inspect and Replace Brake Rotors (if needed)

Inspect Brake Rotors:
- Check for grooves or scoring on the rotor surface.
- Measure rotor thickness to ensure it is within specifications.
Replace Brake Rotors (if necessary):
- Remove the caliper bracket using a socket or wrench.
- Take off the rotor by pulling it straight off the hub. If it is stuck, gently tap it with a rubber mallet.
- Install the new rotor, ensuring it is seated properly on the hub.

5. Reassemble Braking System

Reattach the caliper bracket and torque bolts to manufacturer specifications (usually around 80-100 ft-lbs).
Reattach the caliper over the new pads.
Torque caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs).
Reinstall the wheel and torque the lug nuts to the specified value (typically 75-85 ft-lbs).

6. Lower the Vehicle

Carefully lower the vehicle off the jack stands using the jack.
Tighten the lug nuts fully again if necessary after lowering.
