Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor.
- Check the brake pads for thickness; replace if they are worn below manufacturer specifications (typically 3mm).
Replace Brake Pads:
- If replacement is necessary, compress the caliper piston using a caliper tool.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.
- Reattach the caliper and torque the bolts to the manufacturer's specifications (usually around 20-30 ft-lbs).

5. Inspect and Replace Brake Rotors (if needed)

Inspect Rotors:
- Check for deep grooves or scoring; replace if damaged.
Replace Rotors:
- Remove the rotor by unscrewing any retaining screws.
- Install the new rotor and ensure it is properly seated.
- Reattach the wheel, torque the lug nuts to manufacturer specifications (typically 76-80 ft-lbs).

6. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Pump the brake pedal several times to ensure proper brake pad contact.
Test drive the vehicle at low speeds to confirm that the grinding noise has been resolved.
