Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Park the vehicle on a level surface, engage the parking brake, and ensure the engine is off.
Wear safety glasses and gloves throughout the process.

2. Raise the Vehicle

Use the lug wrench to loosen the lug nuts on the wheel where the grinding noise is occurring (do not remove them yet).
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Remove Brake Components

Brake Pads:
- Remove the caliper bolts using the socket set.
- Carefully slide the caliper off the brake rotor, supporting it with a bungee cord or similar to avoid straining the brake line.
- Inspect brake pads for wear. If the friction material is less than 3mm or if there are grooves, replace them.
Brake Rotors:
- Check the rotor surface. If there are deep grooves or warping, replace the rotors.
- If the rotors are within specifications, clean them with brake cleaner to remove dust and debris.

4. Install New Parts

Brake Pads:
- If replacing, install new brake pads in the caliper bracket, ensuring they are properly seated.
Brake Rotors:
- If replacing, remove the old rotor and install the new rotor, tightening it according to manufacturer specifications (typically 80-100 ft-lbs).

5. Reassemble and Test

Reposition the caliper over the new pads and rotor, then reinstall and torque the caliper bolts to the specified torque (typically 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (typically 75-90 ft-lbs).
