Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks around the rear wheels.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts of the wheel associated with the grinding noise.
Lift the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are less than 3mm, they need replacement.
- Look for uneven wear patterns; this could indicate caliper issues.
Replace Brake Pads:
- Remove the caliper bolts using a socket set, and carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper alignment.
- Reattach the caliper over the new pads and secure with bolts to manufacturer specifications (usually 25-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect:
- Check rotors for grooves, scoring, or excessive wear.
Replace:
- If rotors are damaged, remove the caliper bracket by unscrewing the bolts.
- Remove the rotor from the hub. If stuck, use a hammer to gently tap it loose.
- Install the new rotor, ensuring it seats properly on the hub.
- Reattach the caliper bracket and caliper.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque (typically 76-80 ft-lbs).
Pump the brake pedal to ensure firm pressure before taking the vehicle for a test drive.
