Aircraft
While conducting training operations; as the instructor; in an EMB-500 type aircraft my student had just landed the aircraft and began the rollout on centerline. Upon applying the brakes the said aircraft immediately pulled hard to the left. All attempts to prevent the aircraft from departing the runway were unsuccessful. The aircraft departed the left side of the runway and the left tire struck a runway marker thus breaking it. The aircraft was subsequently brought under control by myself and taxied back onto the runway and then taxied via the remaining runway and taxiways to the ramp for inspection. Inspection of the aircraft revealed a small mark on the left tire but no other damage to the aircraft was visible. Embraer was called to do a full inspection of the aircraft as well as a system download to determine the cause. It was determined by Embraer that a failure of the Brake Control Module was the cause of the rapid and abrupt pulling of the aircraft to the left and said system was repaired by Embraer through replacement parts. The final inspection of the aircraft by Embraer employees revealed no other damage to the aircraft or its systems. No passengers or crew were injured during this event.
Phenom 100 Flight Instructor reported that upon runway roll out; the left brake locked up causing the jet to swerve and leave the hard surface of the runway.
