Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to avoid electrical issues.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts on the front or rear wheel where the grinding noise is observed.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Inspect the brake pads for wear; replace if less than 3mm thick or if there are grooves.
Brake Rotors:
- Check the rotor surface for scoring or grooves. If damaged, replace or resurface them.
- Measure rotor thickness with a micrometer; replace if below manufacturer specifications.

4. Replace Brake Pads and Rotors (if needed)

If pads are worn, install new brake pads:
- Apply brake grease on the backing of new pads.
- Slide the new pads into the caliper bracket.
If rotors are worn, replace with new rotors:
- Remove the old rotor and install the new rotor onto the hub.

5. Reassemble and Test

Reattach the brake caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern.
Lower the vehicle and reconnect the battery.
