It definitely has to react fast in the moment it’s needed and line diameter can have a lot to factor into that.

I actually purchased my first adapter kit from Dave. He’s a good guy, great product and very helpful through when we emailed.

Diagnosing over phone and email can only go so far though then you have to start really diving in to it yourself. I’ve always had the dreaded spongey pedal in this truck but power brakes have helped band aid it enough to make it drivable. So it’s not really a “conversion” problem as much as I’ve just uncovered how poorly mismatched my brakes are lol. Using the stock master cylinder I could only generate about 250-500psi max at the calipers and that’s with me pumping the brakes and shoving myself into the seat.

I changed my approach to one that I’m building a completely new brake system using the calipers I have and matching components from there

Total caliper piston area × mechanical pedal ratio ÷ MC area

So with 190, if you push with 1 lb of force on the pedal, you get 190 lbs of total force pushing the pistons all added together; also, if you move the pedal 1", you get a total movement of all the pistons added together of 1/190". Hydraulic & pneumatic systems work just like a lever in this regard.

Brake line dia makes no difference in this regard. One molecule in at the MC end, one molecule out at the caliper end. Only difference it makes is the amount of fluid that can flow, and how quickly, before the loss from pushing it through becomes an issue.

Sponginess sounds like air in the system more than anything else.
