Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, socket set.
Safety Warnings: Ensure the vehicle is on a level surface and secured with wheel chocks before lifting.

2. Remove Wheel

Loosen the lug nuts on the wheel where the grinding noise originates.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Visually inspect brake pads for wear; replace if less than 3mm thick.
Check brake rotors for any visible scoring, cracks, or warping; replace if necessary.
Examine brake calipers for any signs of sticking or leakage; ensure they move freely.

4. Replace Brake Pads and Rotors (if necessary)

Remove Brake Caliper:
- Use a socket set to remove caliper bolts.
- Suspend the caliper using a bungee cord to avoid straining the brake line.
Remove Old Brake Pads:
- Slide out the old brake pads from the caliper bracket.
Replace Rotors (if required):
- Remove the caliper bracket bolts and take off the bracket.
- Remove the rotor by pulling it straight off the hub.
- Install the new rotor, ensuring it is seated correctly.
Install New Brake Pads:
- Apply brake grease to the backing of new pads (avoid the friction surface).
- Slide the new pads into the caliper bracket.
Reinstall Caliper:
- Reattach the caliper over the new pads and torque the bolts to the manufacturer's specifications.

5. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified torque value.

6. Test Brake Function

Pump the brake pedal several times to ensure the pads seat correctly.
Conduct a short test drive to verify the absence of grinding noise.
