Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Safely raise the vehicle using a jack and support it on jack stands.
Remove the wheel using a lug wrench.

2. Inspect Brake Components

Inspect Brake Pads:
- Remove the brake caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it with a bungee cord or similar.
- Check the brake pads for thickness; replace if less than 3mm.
Check Brake Rotors:
- Examine rotors for grooves or scoring. Measure rotor thickness with a micrometer.
- If the rotor thickness is below specifications or has visible damage, replace it.

3. Replace Brake Pads and/or Rotors

Replace Brake Pads:
- If pads are worn, remove them from the caliper bracket.
- Install new brake pads in the reverse order, ensuring they are properly seated.
Replace Rotors (if necessary):
- Remove the old rotor from the hub by unscrewing any retaining screws.
- Install the new rotor, ensuring it is properly aligned.
- Torque the rotor screws to the manufacturer’s specifications.

4. Reassemble Brake System

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specifications.
Reinstall the wheel and lower the vehicle.

5. Test Brakes

After reassembly, pump the brake pedal to ensure firmness.
Conduct a test drive at low speed to confirm the grinding noise is resolved.
