Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord or similar to avoid strain on the brake line.
- Check the thickness of the brake pads; replace if they are below 3mm.
Replace Brake Pads:
- Slide new brake pads into the caliper bracket.
- Reinstall the caliper over the new pads and secure it with the caliper bolts. Torque to manufacturer specifications (typically around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for grooves, warping, or excessive wear.
Replace Rotors:
- Remove the caliper bracket if necessary.
- Slide the old rotor off the wheel hub.
- Install the new rotor, ensuring it is seated properly on the hub.
- Reinstall the caliper bracket and torque to manufacturer specifications.

5. Final Assembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically around 75-85 ft-lbs).
Repeat the process on the other side if necessary.

6. Test

Pump the brake pedal a few times to ensure proper pad seating.
Take the vehicle for a short test drive to confirm that the grinding noise has ceased.
