Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Raise the front or rear of the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts of the wheel where the grinding noise is occurring.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are worn down to less than 3mm, they need replacement.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord to avoid hanging by the brake line.
- Remove the old brake pads and install new pads, ensuring they are correctly oriented.
- Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for any scoring or damage on the rotor surface. If grooves are felt, rotors may need resurfacing or replacement.
Replace Rotors:
- Remove the caliper bracket if necessary.
- Slide the rotor off the hub.
- Install the new rotor and reassemble the caliper and bracket.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (around 76-80 ft-lbs).
Pump the brake pedal to seat the pads against the rotor.

6. Final Checks

Ensure all components are secure and there are no leaks.
Dispose of old brake pads and any waste material properly.
