Thanks for the response on this. The throw on the pedal should shorten up when pressurizing the system, right? I'm using an fj60 mc with the stock fj40 booster and the system is currently dry. Still building, you see.I was either going to make a brake clutch pair or buy used stock car ones for my triple master setup, they have different leverage ratios available. I think Ive seen single brake apps but you can probably mod the stock one to work with about the same amount of work as cutting to fit an aftermarket one.
For a single app you could move the pivot further up, move the end for the master further down, or change to a bigger bore master cylinder to shorten travel though all of these reduce mechanical or hydraulic advantage making for a stiffer pedal.
