Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, shop towels.
Ensure the vehicle is parked on a level surface, and the ignition is turned off.
Safety Warning: Always wear safety glasses and gloves.

2. Raise the Vehicle

Loosen the lug nuts on the wheels where the grinding noise is occurring.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the brake rotor.
Check the brake pads for thickness; if they are worn down to 3mm or less, replace them.
If replacing, remove the old pads and install new ones, ensuring they are properly seated.
Reinstall the caliper over the new pads and torque the bolts to manufacturer specifications.

4. Examine and Replace Brake Rotors (if necessary)

Check rotors for any signs of scoring or warping.
If damaged, remove the rotor by unbolting it from the hub.
Clean the hub surface with brake cleaner.
Install new rotors, ensuring they are oriented correctly, and torque the bolts to manufacturer specifications.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Once on the ground, use the torque wrench to tighten the lug nuts to the specified torque.
