DC, I couldn't find any good pics of a complete system to better illustrate, but shifters mount both master cylinders side by side with the same long bolts, and then they both connected to the single brake pedal actuating rod with a bias adjuster (like the pic below) so the driver can adjust the front to rear brake bias while he's driving. Its a pretty trick setup, you just turn the knob one way for more front brakes, or the other direction for more rear.
