Whoops,

I made an error.

While dealing with the profound subject of whether the pedal forces got bigger 
or
smaller with the bore of the master cylinder I started typing in the relevant
equations.

The problem was that e-mail only accepts the normal keyboard letters.  The 
actual
formulas involve the ratio of the square of the radii, not the diameter.  When I
tried toying in the equation, in normal engineer/scientific ASCII keyboard
notation, I realized that eyes were going to glaze over.  Those who could follow
the 'code' already knew the answer, and those who didn't would not be
enlightened.  Additionally, most people recognize hydraulic cylinders by their
diameter, and the formulae use radius.

A very short part of the symbols would look like:

F= (( pi x (D1/2)^2) / ( pi x (D2/2)^2)) x (L1/L2)

Well, you get the idea.

So I tried to simplify it by dealing with the diameters only, and squared it
instead of the radius.

Sorry about trying to make it simpler, but the answer is the same, even if the
exact numbers aren't:

Bigger M/C = less travel, more force
Smaller M/C = more travel, less force
