I seem to remember something called a "proportioning valve",
between front and rear brakes.
That's correct and some are adjustable. On those units it is
necessary to balance the system after changing out the master
cylinder.

But aren't the front and rear independent systems, with separate reservoirs
and all? It sounds like this valve is a single point of failure common to
both systems.

Most cars have two independent systems,
right front/left rear and left front/right rear.

Are you nuts, Jim? That would put a car in a spin in seconds flat if
one reservoir were dry. I believe that all the cars I ever worked on
up through the 90s had separate circuits for front and rear. I see no
reason they'd change that. It's a real safety issue.

If you know of crossed systems, please post a link. I gotta see this.

FYI - Alfa Romeo in the early 70's did, the 1750GTV and the 2000GTV
from staring at the engine bay - also had a separate booster on each
set. Why? - no idea, really. Probably a good idea at the time -
