A319 flight crew experienced normal brake failure during taxi out preceded by an 'auto brake fault' ECAM. The anti-skid and nose wheel steering switch is cycled and initially does not restore braking and reverse thrust is used to stop the aircraft. Subsequent antiskid switch resets are successful but only for a short period of time. The aircraft is shut down and towed to the gate. After maintenance releases the aircraft for flight the same the same brake failures reoccur.

Narrative:
The aircraft started out with a normal taxi with the brakes testing good upon initial taxi out. After a very short period of time on taxi out the aircraft ECAM displayed an 'auto brake fault' ECAM and the aircraft subsequently lost normal braking with the green hydraulic system. The 'anti-skid nose wheel steering switch was then used to utilize alternate brakes with the yellow hydraulic system but this also resulted in no brakes. Not knowing if the flight attendants were standing up in the aisles the thrust reversers were used to slow the aircraft down enough to apply the parking brakes without abruptly stopping the aircraft. We received the 'auto brake fault' light three times with intermittent total loss of normal and alternate braking while using the above method to safely stop the aircraft. The aircraft was stopped safely and coordination was made with maintenance and dispatch to have the aircraft towed back to the gate.the passengers were taken off the aircraft and maintenance checks and resets of the braking system were performed by maintenance. The aircraft was eventually cleared by maintenance and returned the aircraft to service. We were then tasked to fly the same aircraft and the exact same loss of normal and alternate braking occurred. The same methods mentioned above were used to safely stop the aircraft and tow the aircraft back to the gate.
