Abstract

A pneumatic brake system for a heavy duty vehicle is provided. The work brake system is operably dependent on a predetermined high trip brake system pressure and a predetermined reset brake system pressure. Upon actuation of the work brake system, when brake system pressure is greater than the predetermined high trip pressure, the work brake system is configured to deliver a pneumatic control signal to the second control valve to activate the service brake assembly. When brake system pressure is less than the predetermined high trip pressure, the work brake system is configured to deliver a pneumatic spring brake signal to the first control valve to activate the spring brake assembly and remove the pneumatic control signal to the second control valve. The delivery of the pneumatic control signal to the second control valve via the work brake system is prevented until brake system pressure exceeds the predetermined reset pressure.
