I don't think most break dust comes from the rotors. Unless they're really soft units & made from fairly week steal. Some cars go 60-70k + before the rotors ever need servicing / down to minimum thickness for replacement. But there's no way the pads will last that long (depending on how you drive). There's ton's more pad material loss there than ever is rotor material degradation.
