The invention relates to an electropneumatic service brake device (1) for a vehicle, at least comprising: at least one first pneumatic service brake cylinder (BZ1) that can be acted on by a first service brake pressure (p1), and at least one second pneumatic service brake cylinder (BZ2) that can be acted on by a second service brake pressure (p2), a foot brake actuator (5), a pneumatic foot brake valve device (FBV; FBM) for generating a first control pressure (Stp1) and a second control pressure (Stp2) depending on an actuation of the foot brake actuator (5), an electronic service brake control (EBS-ECU), which is designed and configured to generate, depending on an electrical brake request signal, an electrical control signal which represents a target service brake pressure, a first electropneumatic solenoid valve device (2C-EVO), which is provided and designed to be electrically controllable by the electrical control signal or pneumatically controllable by the first control pressure (Stp1), a second electropneumatic solenoid valve device (FAM), which is controlled by the electronic service brake control (EBS-ECU) and designed to generate the second service brake pressure (p2) for the at least one second service brake cylinder (BZ2). According to the invention, the second electropneumatic solenoid valve device (FAM) is designed differently from a pressure control module, such that the second service brake pressure (p2) for the at least one second service brake cylinder (BZ2) can be generated in a plurality of operating modes, which ensure redundant generation of the second service brake pressure (p2) and stability control and/or driving dynamics control.
