A pneumatic emergency brake assurance module comprises a high capacity transfer valve connected in a first position to the output of the variable load relay valve and in a second position connected to a source of emergency braking air pressure. A timing reservoir is in communication with the pilot port of the high capacity transfer valve. A check valve/choke circuit provides parallel connections between a double check valve and the output of the variable load relay valve such that flow from the variable load relay valve passes through a charging choke and opposite flow to the variable load relay valves passes through a dissipation choke.
