An EMB145's normal braking system failed on landing with no EICAS or other indications. Maximum reverse and emergency brakes were used to stop the aircraft causing all four main tires to deflate.

Narrative:
During the landing roll the normal brakes failed. Reverse thrust and emergency braking was used to stop the aircraft on the runway. The conditions for the landing was day VMC on a dry runway. The aircraft remained disabled on the runway and all passengers and crew were deplaned and bussed to the terminal. No injuries were reported. During the landing roll out the aircraft's normal hydraulic brakes failed. There were no EICAS indications of any system failure. The failure was recognized when the aircraft stopped decelerating on the runway with the rudder/brake pedals applied at their maximum. To compensate for the loss of normal braking; maximum reverse thrust was used and eventually emergency braking via the parking/emergency brake.
