Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery (negative terminal) for safety.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Lift the vehicle with the jack and secure it with jack stands.
3. Completely remove the lug nuts and then take off the wheel.

3. Inspect Brake Components

Tools Required: Caliper tool, torque wrench.
Sub-steps:
1. Visually inspect brake pads; replace if less than 3mm thick.
2. Check rotors for grooves and uneven surfaces; resurface or replace as necessary.
3. Inspect caliper functioning; ensure it slides freely and is not seized.

4. Replace Brake Pads and Rotors (if necessary)

Tools Required: Brake pad spreader, socket set.
Sub-steps:
1. Remove caliper bolts and lift the caliper away from the rotor.
2. Remove old brake pads from the caliper bracket.
3. If replacing rotors, remove the rotor by unbolting it from the hub.
4. Install new rotors and torque the bolts to manufacturer specifications.
5. Insert new brake pads into the caliper bracket and compress the caliper piston using a caliper tool.
6. Reattach the caliper and torque bolts to specifications.

5. Reassemble and Test

Tools Required: Lug wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and tighten lug nuts to manufacturer specifications.
3. Reconnect the battery and perform a test drive to ensure the grinding noise is resolved.
