I know this has come up a lot, but after searching a bit, I still have an unanswered question.
If I had the room, like by moving the master cyl, why not run a conventional style vacuum boosted dual res master cylinder.
Provided you could link it to the brake pedal, is there a reason why not? Doesn't it work basically the same way as the hydrovac?
The master of coarse would need to be one that would work with drum/drum brakes and the correct bore size. (haven't got that far yet)
This is on my 52 2t dump truck, it's brakes need a complete overhaul anyway.
