For those that are modifying thier brakes, this seem like a good resource for making it work right.

If anyone knows the math behind all, this it would make me very happy to know it

Dave, the math is fairly simple: divide the area of the caliper piston by the area of the MC piston, and that will give the ratio referred to in your link. For example:

38mm caliper piston- 19x19=361, x3.14=1133.54 sq mm
10mm MC piston- 5x5=25, x3.14= 78.5 sq mm
1133.54/78.5=14.44 ratio

Sorry, didn't actually state what I wanted to know. It happens when I'm tired.
From what I've read there is a bit more to calculating a good braking setup. The other variables would be wheel, and rotor diameter. Unfortunately I can't seem to find any information on that portion.
