Brake Pressure Booster

I am concerned with running out of pedal travel before I get a full stop.
The pedal is wide enough so I can stand on it with both feet to get the
extra pressure, but it does not work if I have run out of pedal travel.
This system sacrifices some pedal travel for the incresed brake pressure
with lower pedal pressure?
Is there anyone working on an anti-lock braking system for the rear axle?

It might be worth trying the pressure multiplier with a P-30 (34mm) master
cylinder to compensate for the extra displacement.

It's not widely known, but Leigh Harrison put ABS on his GMC many years
ago; in fact, I think he told me that all of his brake kits had provision
for the rotation sensors, never populated. He said it was just too
complicated for him to try to support it.
