A redundant pneumatic brake control system for use in a vehicle (1) comprising service brakes (12) and spring brakes (11), comprising an electro-pneumatic parking brake module, EPB (13), a first pneumatic connection (15), a second pneumatic connection (16), a pressure control valve, PCV (14) and control arrangement (10). The second pneumatic connection is arranged to connect the EPB to a control port (122) of a pneumatic control module, PCM (121), such that the generated EPB pressure regulates a control pressure present at the control port. The control arrangement is configured to perform independent control of the pressure-actuated spring brakes and service brakes by alternately controlling the PCV to the open position and the closed position, based on a difference in step response of the first and second pneumatic connections, while controlling a level of the EPB pressure.
