Solution

1. Preparation

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

2. Remove Wheel

Using a lug wrench, loosen the lug nuts on the wheel where the grinding noise is occurring.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Inspect Brake Pads:
- Remove the brake caliper bolts using a socket set.
- Slide the caliper off the rotor carefully and hang it using a bungee cord.
- Check the brake pads for thickness. Replace if less than 3mm.
Inspect Brake Rotors:
- Check for deep grooves or scoring on the rotor surface.
- If the rotor is damaged, make a note of the thickness and consider machining or replacing it.

4. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and install new brake pads in the same orientation as the old ones.
Apply a thin layer of anti-squeal lubricant to the back of the new pads.

5. Reassemble Components

Reinstall the brake caliper over the new pads and secure it with caliper bolts. Torque to manufacturer specifications (typically around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (usually around 100-150 ft-lbs).

6. Test the Brake System

Pump the brake pedal several times to seat the pads.
Check brake fluid level and top off if necessary.
Conduct a test drive to ensure the grinding noise is resolved.
