Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it using wheel chocks.
Wear safety glasses and gloves.

2. Lift and Secure the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the grinding noise is occurring.
Secure with jack stands to prevent the vehicle from falling.

3. Remove the Wheel

Use a socket set to remove the lug nuts from the wheel.
Carefully take off the wheel and set it aside.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Carefully lift the caliper away from the rotor.
- Check the thickness of the brake pads; if they are below 3mm, replace them.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Insert new brake pads into the bracket, ensuring they are seated properly.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check the surface of the rotor for deep grooves or scoring.
- Measure rotor thickness; if below specifications, replace rotors.
Replace Rotors:
- Remove the caliper bracket if necessary, then remove the rotor.
- Install new rotors, ensuring they are properly aligned and secured.

6. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer torque specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to the specified torque (typically around 76-80 ft-lbs).

7. Lower the Vehicle

Remove jack stands and lower the vehicle using the jack.
Tighten lug nuts to the specified torque again after lowering.
