Solution

1. Preparation

Gather necessary tools and parts.
Make sure the vehicle is on a flat surface and secure it with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Loosen lug nuts on the affected wheel using a lug wrench.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect Brake Components

Check the brake pads:
- If worn down to the indicator, replace them.
Inspect the brake rotors:
- Measure rotor thickness with a micrometer. If below specifications (typically 1mm) or scored, replace or resurface.
Examine calipers:
- Ensure they are not sticking; clean or lubricate sliding pins if necessary.

4. Replace Brake Pads and/or Rotors

If replacing brake pads:
- Remove the caliper bolts with a socket set and slide the caliper off.
- Remove old pads and install new pads in the caliper bracket.
If replacing rotors:
- Remove the brake rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install the new rotor and secure it with screws.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specification (usually around 75-85 ft-lbs).

6. Final Check

Pump the brake pedal several times to seat the pads.
Test drive the vehicle to ensure the grinding noise is resolved.
