Sub-steps:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Remove the lug nuts completely and take off the wheel.

4. Inspect Brake Components

Tools required: Torque wrench (for reinstallation).
Sub-steps:
1. Visually inspect the brake pads for thickness; replace if below 3mm.
2. Check the rotors for grooves or discoloration; replace if necessary.
3. Inspect calipers for leaks or sticking; clean or replace if needed.
