Solution

1. Preparation

Gather necessary tools and parts as indicated below.
Ensure the vehicle is parked on a flat surface, and set the parking brake.

2. Remove Wheel

Use a jack to lift the front or rear end of the vehicle (depending on where the noise is coming from).
Secure the vehicle with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads for wear. Replace if less than 3mm thick.
Check the brake rotors for grooves or discoloration. Replace if damaged or excessively worn.
Inspect the brake calipers for proper function. Ensure they are not sticking or leaking fluid.

4. Replace Brake Pads

If brake pads are worn, remove the caliper mounting bolts with a socket wrench.
Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly.

5. Replace or Resurface Rotors (if necessary)

If rotors are damaged, remove them from the hub by unscrewing the retaining screws (if applicable).
Install new rotors, or if resurfacing, ensure they meet the manufacturer's specifications for thickness and flatness.

6. Reassemble Brake Components

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (typically 15-25 ft-lbs).
Reattach the wheel and torque lug nuts in a star pattern to manufacturer specifications (typically 100-120 ft-lbs).

7. Test Brakes

Lower the vehicle and pump the brake pedal to seat the pads against the rotors.
Conduct a test drive to ensure the grinding noise is resolved and brakes function properly.
