1. A brake system comprising:
a plurality of braking modules, each braking module including a housing forming at least one manifold for the delivery of fluid through the module to at least one brake;
at least one of the braking modules configured for coupling to a pressurized fluid source to provide fluid at a system pressure and coupling to a tank fluid source to provide fluid at a tank pressure;
each braking module including:
a hydraulic valve positioned in the housing and coupled with the pressurized fluid source for delivering fluid through the module to the at least one brake to implement a braking function;
an electro-hydraulic valve positioned in the housing and coupled with the pressurized fluid source, the electro-hydraulic valve configured for receiving electrical input signals and, in response to the input signals, configured for delivering fluid from the pressurized fluid source at an actuation pressure to the hydraulic valve, the actuation pressure being proportional to the system pressure based on the levels of the received electrical input signals;
a plurality of module interfaces positioned on respective sides of the housings for coupling the braking modules together, the module interfaces including a repeated pattern of apertures in the housing for aligning between coupled braking modules, the aligned apertures configured for passing fluid at the system pressure and fluid at the tank pressure between the plurality of braking modules.
