The present invention is a fast acting pneumatic brake system for vehicles. The system includes an pneumatic spring brake operatively coupled to a first and second air tank via supply and constant pressure air lines, respectively. A pneumatically controlled central air valve is operatively coupled to the supply air line. The central air valve is operatively coupled to a hand valve which controls the operation of the central valve. A first electrically controlled air valve is operatively coupled to the supply air line between the pneumatic spring brake and the pneumatically controlled air valve. The first electrically controlled valve is a normally open valve which closes only when energized. A second electrically controlled air valve is operatively coupled to the constant pressure air line between the pneumatic spring brake and the second air tank. The second electrically controlled air valve is a normally closed valve which opens only when energized. The system includes a control circuit for simultaneously energizing the first and second electrically controlled air valves.
