Shimano use mineral oil in all their brakes. The proper stuff is pretty thin, and specially formulated (so Shimano claim anyway) to have a quite high boiling point. Baby oil could be used in an emergency, but its higher viscosity could affect performance, and may have a lower boiling point than the proper stuff.
