A brake system to couple between brakes and actuators provides a modular format that allows a plurality of braking modules (12, 14, 16, 18) to be coupled together at interfaces and coupled to other modules to handle a variety of different braking scenarios. Each braking module (12, 14, 16, 18) includes a housing (54, 56) forming a manifold for the delivery of fluid to the interfaces (90) of the modules for exchange between the modules. The braking modules (12, 14, 16, 18) include a hydraulic valve (68) coupled with a pressurized fluid source for delivering fluid to implement a braking function. The modules (12, 14, 16, 18) also include an electro-hydraulic valve (50, 52) configured for receiving electrical input signals and configured for delivering fluid from the pressurized fluid source to the hydraulic valve (68) at an actuation pressure that is proportional to the system pressure based on the levels of the received electrical input signals. Module interfaces (90) are positioned on respective sides of the housings (54, 56) for coupling the braking modules (12, 14, 16, 18) together and include a repeated pattern of apertures (100) for aligning between the braking modules (12, 14, 16, 18). The aligned apertures (100) are configured for passing fluid at the system pressure and fluid at the tank pressure between the plurality of braking modules (12, 14, 16, 18).
