In theory the anti-skid should prevent those skid marks near the end. But if they went for the Emer Brake that could have done it.
There was a Phenom 300 that landed in heavy rain, thought they had lost normal braking, and applied emer brakes. All they did was steam clean the runway before going off the end.
Operator came out with a new policy that prohibited use of emer brakes unless there was a CAS message for normal brakes.
