Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, lug wrench, brake cleaner, torque wrench, OBD-II scanner.
Allow the vehicle to cool down and ensure it is on a level surface.
Disconnect the negative battery terminal to prevent any electrical issues during work.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts on the wheel with the braking issue.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspecting Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it to avoid straining the brake line.
- Inspect brake pads for thickness; if less than 3mm, they should be replaced.
Replacing Pads:
- Remove the old pads from the caliper bracket.
- Apply brake grease to the backing of the new brake pads to prevent squeaking.
- Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspecting Rotors:
- Check the surface of the rotors for deep grooves or scoring.
- Measure rotor thickness; if below specifications, they should be replaced.
Replacing Rotors:
- Remove the caliper bracket if rotors need replacing using the socket set.
- Slide the rotor off the hub; if stuck, gently tap with a rubber mallet.
- Install the new rotor onto the hub, ensuring it is seated properly.

5. Reassemble and Torque

Reinstall the caliper bracket to the rotor and torque the bolts to manufacturer specifications (generally around 80-100 lb-ft).
Reattach the caliper over the new pads and torque the caliper bolts to the specified value.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque (usually 100-120 lb-ft).
Reconnect the negative battery terminal.
Test drive the vehicle to ensure the grinding noise has resolved and brakes are functioning properly.
