- Use a lug wrench to remove the lug nuts and take off the wheel.
- Keep lug nuts in a safe place for reinstallation.

4. Inspect and Replace Brake Components

Sub-steps:
- Check the thickness of the brake pads; replace if they are below the manufacturer's minimum specification (usually around 3mm).
- Inspect the brake rotors for grooves or warping; replace if damaged.
- If necessary, clean the brake calipers and inspect the caliper slides for smooth operation. Lubricate as needed.
- Install new brake pads and rotors if applicable, ensuring they are properly seated.

5. Reassemble and Test

Sub-steps:
