it has Russel braided flex lines that I put on probably 4 or 5 years ago. I’ll go around and check that something didn’t damage them while the wife pumps the brakes.

I’m gonna look for some kind of calculation similar to finding brake PSI. When I did my braking psi calculation, everything checked out but volume may be another story and the math doesn’t lie.

I found a brake calculator of sorts today and started fiddling with it. It’s an excel work sheet from Busted Knuckles Off Roads website. Going by their guidelines I should be aiming for an overall leverage of around 190 for manual brakes.
With all my stuff plugged in I’m at 119 with a stock bore size (1.338”) and a 6.4:1 pedal ratio. Not good.
Now if I drop the bore size down to 1 inch, I get about a 212 overall leverage. Much better and that’s a 78% gain.
Guess I’ll be looking for a smaller master cylinder.

Here is the brake calculator that I used when I upsized my MC and rear calipers: https://www.tceperformanceproducts.com/bias-calculator/
I agree that it sounds like your Master Cylinder size may be too large diameter.
