Sub-steps:
- Check the brake rotors for any scoring or excessive wear.
- If the rotors are damaged, remove them by unscrewing the retaining screws and sliding them off the hub.
- Install new rotors, ensuring they are properly aligned and secured with screws.

5. Reassemble and Finish

Sub-steps:
- Reinstall the brake caliper over the new pads and rotor, securing it with the caliper bolts.
- Reattach the wheel and tighten the lug nuts to the manufacturer’s torque specifications.
- Lower the vehicle from the jack stands and reconnect the battery if disconnected.
