Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Wheel Removal

Using a socket set, loosen the lug nuts of the wheel associated with the grinding noise.
Lift the vehicle with a jack, then secure it with jack stands.
Remove the wheel completely.

3. Brake Pad and Rotor Inspection

Remove the caliper by unbolting it with a socket wrench.
Carefully slide the caliper off the rotor and support it using a wire or bungee cord (do not let it hang by the brake line).
Inspect brake pads for wear. If the friction material is less than 3mm thick, replacement is necessary.
Check the rotor for scoring or uneven wear. If grooves or significant wear is present, the rotor will need resurfacing or replacement.

4. Replace Brake Pads

If necessary, remove the old brake pads from the caliper bracket.
Apply brake grease to the backing of the new pads to prevent noise.
Install the new brake pads into the caliper bracket.

5. Rotor Replacement or Resurfacing

If the rotor is damaged, remove it by unbolting it from the hub.
Install the new or resurfaced rotor, ensuring it is properly seated.

6. Reassemble Brake Components

Reattach the caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer’s torque specification (generally around 25-30 Nm).
Reinstall the wheel and tighten the lug nuts in a crisscross pattern.

7. Final Checks

Lower the vehicle from the jack stands.
Pump the brake pedal several times to seat the brake pads properly.
Check brake fluid levels and top off if necessary.
