Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Inspect Brake Components

Check Brake Pads:
- Remove the caliper bolts with the appropriate socket.
- Carefully lift the caliper and support it (do not hang it by the brake line).
- Inspect the brake pads for thickness; they should be at least 3mm thick. Replace if worn.
Check Brake Rotors:
- Inspect the rotor surface for scoring or deep grooves.
- If the rotor is warped or has excessive wear, it should be resurfaced or replaced.

3. Replace Brake Pads (if necessary)

If pads are worn, remove them from the caliper bracket.
Apply brake grease to the back of the new pads to prevent noise.
Install the new brake pads into the caliper bracket.

4. Reassemble Braking Components

Reinstall the caliper over the new brake pads.
Torque the caliper bolts to the manufacturer’s specifications (typically around 25-35 Nm).
Reinstall the wheel and lower the vehicle.

5. Test Brakes

Pump the brake pedal a few times to seat the new pads against the rotors.
Conduct a test drive to ensure the grinding noise has ceased and braking performance is restored.
