A vehicle brake system includes a source of fluid pressure adapted to supply a braking force to at least one brake actuator and a modular valve unit fluidly coupling the brake actuator to the source of fluid pressure. The modular valve unit includes a plurality of valve modules. Each of the plurality of valve modules includes a housing in which working elements of the valve module are contained and at least one port in the housing adapted to be an input port or an output port, the at least one port being adapted to cooperate with and be directly fluidly connected to at least one port of another of the plurality of valve modules, thereby obviating the need for tubing or piping. Each of the plurality of valve modules is self-contained and defines a stand-alone unit capable of operating independently of any other of the plurality of valve modules.
