Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent the vehicle from rolling.

2. Lift the Vehicle

Tools Required: Jack and jack stands.
Sub-steps:
1. Use the jack to lift the front or rear of the vehicle, depending on where the grinding noise is coming from.
2. Secure the vehicle with jack stands.

3. Remove Wheel

Tools Required: Lug wrench.
Sub-steps:
1. Loosen the lug nuts on the wheel corresponding to the grinding brakes.
2. Remove the lug nuts and take off the wheel.

4. Inspect and Replace Brake Components

Tools Required: Socket set, brake cleaner, and a torque wrench.
Sub-steps:
1. Remove the brake caliper by unscrewing the caliper bolts.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
3. Remove the brake pads from the bracket.
4. Inspect the rotors for any grooves or damage; replace if necessary.
5. If pads are worn down to the metal, replace them with new ones.
  - Use brake cleaner to clean the caliper and bracket.
6. Install new brake pads into the bracket and reattach the caliper.
7. Torque caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs).

5. Reassemble

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and then torque the lug nuts to the appropriate specification (usually around 76-83 ft-lbs).

6. Test Brakes

Sub-steps:
1. Pump the brake pedal a few times to ensure the caliper seats properly against the pads.
2. Test drive the vehicle at low speeds to ensure proper brake function and to check for grinding noise.
