Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent accidental electric discharge.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads; they should be at least 3mm thick.
Replacement:
- If worn, remove the caliper bolts with a socket set.
- Slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection:
- Check rotors for grooves or warping with a straight edge or micrometer.
Replacement:
- If damaged, remove the caliper bracket using a socket set.
- Slide off the rotor; if stuck, use a rubber mallet to gently tap it off.
- Clean the hub surface with brake cleaner to ensure proper contact with the new rotor.
- Install the new rotor, aligning it with the wheel hub.

5. Reassemble Components

Reattach the caliper bracket and caliper; torque the bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

6. Final Check

Reconnect the battery.
Press the brake pedal a few times to ensure proper pad seating.
Test drive at a low speed to confirm that the grinding noise is resolved.
