I don't know how the anti-skid brake system is designed. But on the older systems, brakes are a dual mostly-independent system. There was one system for the front brakes, and another for the rear. Dual cylinders, dual reservoirs, etc. The brake pedal operated both cylinders. There was even a hydraulic comparator between the two, which would turn on a red [brake] light on the dash if they differed in pressure.
Last year, I acquired a leak in my rear brakes on my old truck, and that light coming on was my first indication of trouble. The front brakes still worked fine, and topping off the rear reservoir got the rear brakes temporarily working, and I was able to ease it to the repair shop without difficulty.
It's a good example of how to build a safe, fault tolerant system.
