Solution

1. Preparation

Gather necessary tools and parts.
Safely lift the vehicle using a jack and secure it with jack stands.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel associated with the grinding noise.
Carefully remove the wheel and set it aside.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are less than 3mm, they need replacement.
Replace Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully lift the caliper off the rotor and support it with a bungee cord or similar device (do not let it hang).
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are securely in place.
- Reinstall the caliper and tighten the caliper bolts to the manufacturer’s specified torque (typically 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for uneven wear, scoring, or warping.
Replace Rotors:
- If replacement is necessary, remove the caliper bracket and then the rotor retaining screws if present.
- Slide the old rotor off the hub and install the new rotor.
- Reattach the caliper bracket after the new rotor is in place.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 100-150 ft-lbs).
Pump the brake pedal to seat the brake pads before driving.
