When did seperate hydraulics start being common? Most of the vehicles ive worked on have one hydraulic system with a proportioning valve to control pressure, usually with more braking power going to the front.
I wouldn’t really consider that 2 seperate systems. If your front brakes leak you’re still gonna end up losing pressure to the rear. Its pretty much just enough to pull over if you clue in to whats happening

1970s/early 80s. The master cylinder has two chambers, though they are connected.

that is what I was trying to say, but perhaps I didn’t write well.
