But you really need to tell us the model aircraft involved and see if anyone here has some expertise in it.

NetJets had a Phenom that landed during a rain storm in Texas. They were hydroplaning big time. Applying the normal brakes they didn't seem to be slowing down. Thinking they had a malfunction they applied the Emer Brakes, which have no anti-skid. All they did was steam-clean the runway prior to going off the end.
