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 gloves and goggles.

2. Lift the Vehicle

Use a floor jack to lift the front or rear of the vehicle, depending on where the grinding noise is originating.
Secure the vehicle with jack stands.

3. Remove the Wheel

Use a lug wrench to loosen the lug nuts and remove the wheel.
Set the wheel aside in a safe location.

4. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness of the brake pads. If they are worn down to 1/8 inch or less, they should be replaced.
Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the brake rotor and support it with a bungee cord (do not let it hang by the brake line).
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they fit snugly in the bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition: If the rotors are warped or severely scored, they should be replaced.
Remove Brake Rotor:
- Remove any retaining screws if applicable.
- Slide the rotor off the hub.
Install New Rotor: Place the new rotor onto the hub and secure it with screws.

6. Reassemble

Reinstall the brake caliper over the new brake pads.
Tighten the caliper mounting bolts to the manufacturer’s specified torque value (typically around 15-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specifications (usually around 76-80 ft-lbs).
