Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect:
- Check the thickness of the brake pads; if less than 3mm, replace.
- Look for signs of uneven wear or damage.
Replace:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and secure it with a bungee cord or similar.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper alignment.
- Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specification (typically around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect:
- Examine the rotors for grooves or excessive wear.
Replace:
- Remove the caliper bracket if necessary, and unbolt the rotor from the hub.
- Clean the hub surface before installing the new rotor.
- Install the new rotor and torque the bolts to the manufacturer's specifications (usually around 80-100 ft-lbs).

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
Repeat the process for the other side if needed.

6. Test Braking System

Start the vehicle and pump the brake pedal a few times to seat the pads.
Test drive to ensure the grinding noise is eliminated and brakes function properly.
