There's no actual electrical circuitry involved- just two brake lines coming out of the master cylinder instead of one.
From Car & Driver:
"Upon reviewing this list, it is interesting to note that in 1964 SAAB had a dual diagonal braking system. A dual braking system is specified by the General Services Administration as one of the requirements for any cars this government agency purchases in 1967. Generally, dual braking systems control two front wheels and two back wheels separately. SAAB's dual diagonal system controls the left front and right rear; right front and left rear, for greatly improved control.
This same braking system was recently singled out by NASA (National Aeronautics and Space Administration ) in its report to Congress. The space agency rated this braking system "vastly superior" on wet pavement to many U. S. cars'.
The braking tests were conducted by Langley Research Center investigators as part of their study of aquaplaning (the problem of "water ski" effects which can cause aircraft -and cars-to lose all braking and directional control on wet or slushcovered surfaces).
A NASA representative testified that in cars where dual master brake cylinders are used, the "almost universal practice" is to connect the front wheels to one master cylinder and the rear wheels to the other. He added: "A failure of one system gives front wheel braking or rear wheel braking, both of which can result in an uncontrolled skid if wheels are locked on wet pavements."
The Langley investigators noticed that one foreign car (SAAB) had dual master brake cylinders with each serving one front wheel and the diagonal rear wheel. According to the NASA authorities, "the Langley test car with the diagonal hookup was vastly supelior to the other connections for locked wheel conditions on wet pavements." "
