Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen lug nuts slightly.
Lift the vehicle using a jack and secure it with jack stands.
Remove lug nuts completely and take off the wheel.

3. Inspect Braking Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Inspect brake pads for thickness; replace if less than 3mm.
Brake Rotors:
- Check the rotor surface for any scoring or grooves.
- If damaged, replace the rotor with a new one.

4. Replace Brake Pads (if needed)

Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated.
Apply brake grease to the backing of the pads to reduce noise.

5. Reassemble Components

Slide the caliper back over the rotor and pads.
Reattach caliper bolts and tighten to manufacturer specifications (typically 20-25 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern.

6. Test the Brakes

Lower the vehicle and remove jack stands.
Pump the brake pedal to ensure proper contact and feel.
Test drive the vehicle at low speeds to confirm the grinding noise is resolved.
