<VV> more brakes: question

Interesting. A few years ago a front brake hose blew on my 92 Silhouette.
To my surprise, it was as if I had almost no brakes at all. Pedal to floor and
at best a slight drag. Before I convert any of my pre 67 Vairs, I would like
to know if dual master cylinders are worth having.? How should one work in the
event of a failure provided all other components are in perfect working order?
Does anyone in VV land actually know? I'm looking for factual information
here, not just opinions.
Thanks

This might not help...
The dual master cylinder concept is fine in theory but in practice
it's not always that functional. I've been doing this stuff for a
while, and I've done a bit of brake work in my times.
Back When, I installed a dual master cylinder, big brakes, swapped
out all the lines etc on my first '66 Plymouth Satellite. Along the
way I had a wheel cylinder cup leak and by the time I could get it
home I had almost no brakes, front bowl was empty, rear bowl fine,
still almost no brakes, best it would do was slowly "drag" to a stop
with pedal to the floor. After fixing the master cylinder, brakes
were fine. Ditto my brother's '67 Dodge Coronet, which had a leaky
rear wheel cylinder, emptied the MC bowl and HE had practically no
brakes. Another adventurer I knew had a '69 Super-Bee all tricked
out, removed the self-adjusters because "they make the brakes drag a
little and it slows me down". Uh huh. One of the brake shoes'
hardware came loose (either too much slack or installed wrong) and
the cylinder blew out, front right, and HE had no brakes, nearly put
him into a ditch.
Now: One of the 'Vairs here had a similar situation, leaky wheel
cylinder, drained the MC bowl, brakes were barely functional and
pedal was on the floor. Someone else with a '69 500 coupe, similar
situation, empty MC bowl, almost no brakes.
The dual MC is no guarantee you're still gonna have anything
resembling effective brakes on one end or the other if something
fails. The best you can expect is marginal (if that) braking ability
with what you have left.
At least this is my experience.
