That is the other side of the equation to your force diagram. Woody
They are not the same, the SRT pistons have a total area greater than the NA. That means if the MC is the same on both the pedal travel is greater on the SRT.
If the pedal linkage is the same as well then we ar more or less on an even footing.
The psi on a piston does not change because there is a greater piston area, the piston just needs more oil to move it the same amount.
