Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, OBD-II scanner (if needed).
Safely park the vehicle on a level surface and engage the parking brake.
Gather necessary tools and replacement parts.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a lug wrench.
Lift the vehicle using a jack and securely place jack stands beneath.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Sub-steps:
- Inspect brake pads for thickness; replace if less than 3mm.
- Check the brake rotors for any signs of scoring or warping; replace if necessary.
- Look for any debris in the caliper assembly that may be causing the grinding noise.

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
- Remove the caliper by unbolting it from the mounting bracket.
- Slide out the old brake pads from the caliper bracket.
- If replacing rotors, remove the rotor by unscrewing any retaining screws and sliding it off.
- Install new rotors (if applicable) and then new brake pads, ensuring they fit correctly.
- Reinstall the caliper and torque the mounting bolts to manufacturer specifications.

5. Reassemble and Test

Reattach the wheel, hand-tighten the lug nuts, and lower the vehicle.
Torque the lug nuts to the manufacturer’s specifications.
Test the brakes by pressing the pedal a few times to seat the new pads.
