Technical brake pedal ratio from treadle vac setup

Hello I was wondering how to properly calculate the pedal ratio if I have 2 pivots. one at the pedal itself and then another pivot in the rod going to the master. I am installing a remote electric powered booster with master in place of the original non firewall mount treadle vac setup.

 

Divide the long one by the short one and there is ratio. FYI best to do an introduction as soon as possible as per HAMB rules.

 

Thanks but what if I have a second pivot(lever) after the pedal. Is the ratio determined by the pedal or the second pivot? Or both and if both how do I calculate? Do I simply add the ratios for an "overall" ratio?

It seems like your pedal operates another lever, and if that's correct, you figure the ratio of each lever, and multiply the ratios to arrive at the final overall ratio.

 

Ok thank you
