In the late 80's GM had what they called "quick take up" master cylinders, they had stepped bores that were much larger to get the pads to the rotors quickly then a smaller bore for the actual pressure generation. So there was certainly some effort put into the idea.
Not sure what was done on the caliper end of the system because as far as I know they (mostly) all interchange (GM 1/2 ton trucks circa 70's to early 90's), maybe it was just the MC that did the trick??
