[speedy]

i have read the thread and done the mechanical advantage calculations , but am confussed , i understand the ratio of mc to caliper size but if we have a split bore mc and the front and back pistons move the same amount the 23 will displace more fluid in comparison to the 19 for the same amount of movement , the pressure that can be applied is regulated by the 23 piston because of its bigger size according to the formulea (lower ratio).does this make sense or am i missing something . i aggree the 19 can apply a higher ratio of hydralic pressure but cannot displace as much fluide when on the same shaft as a 23mm piston .Does the 944 front and back pistons work independantly , this is the only possible solution i can think of . Can somebody please clarify the answer or am i going nuts
