Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Wear safety glasses and gloves.

2. Wheel Removal

Loosen the lug nuts on the wheel where the grinding noise is present.
Use a jack to lift the vehicle and securely place it on jack stands.
Remove the wheel by taking off the lug nuts completely.

3. Brake Pad Inspection and Replacement

Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Inspect the brake pads for wear; if less than 1/8 inch of material remains, replace them.
If replacing, pull the old pads out and install the new pads, ensuring they are oriented correctly.
Apply brake grease to the backing of the pads to reduce noise.

4. Rotor Inspection and Replacement

Check the rotor surface; if it is scored or warped, it must be replaced or resurfaced.
If replacing, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor, ensuring it is properly seated.

5. Reassembly and Brake System Bleeding

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to manufacturer specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and lower the vehicle.
Pump the brake pedal several times to ensure proper pad seating and to build brake pressure.
If brake fluid was lost, bleed the brake system to remove air.
