    Apparently not. Bigger pistons equals more power. That is why the fronts overpower the rears. There is nothing more to be said on the subject. It is so basic that I can't believe we've wasted this many words already.


    No need to do any experiments or extrapolate strange ideas into something convinving. Read the damn reports filed by brake engineers. The best information available is right in front of you and you can't be bothered to read it because you'd rather make up asinine scenarios.

    I understand what you're trying to say and it is incorrect. If it was a flow based system you could be on to something but it isn't - it is pressure based and therefore the amount of fluid required to move larger pistons is irrelevant.

    The white papers aren't theory or conjecture or up for debate. They are pure post experiment physics.

    We cannot achieve the future by being timid. It requires aggressive imagination.

    really dude.

    wikipedia:

    An interesting aspect of hydraulic systems is the ability to apply force multiplication. Imagine if cylinder one (C1) is one inch in diameter, and cylinder two (C2) is ten inches in diameter. If the force exerted on C1 is 10 lbf, the force exerted by C2 is 1000 lbf because C2 is a hundred times larger in area (S = πr²) as C1. The downside to this is that you have to move C1 a hundred inches to move C2 one inch.
    its a fundimental property of hydraulic systems. you are essentially trading distance for force. changing the output piston size means that piston wont displace as much. (im not going to explain why tolerances require a certain displacement of brake piston on the output, thats basic mechanical engineering.)

    like i said above, i dont think you're getting the fundimentals of what is going on. maybe its my fault for assuming everyone has an engineering background, and im sorry for that.
