Armand,
It works the other way around: if you were to step on a coffee can sized
Master cylinder, with 100 lbs, force, you would move a lot of fluid,
distributed over a large area. If you step on a pill bottle full of fluid
with the same force, you focus the same weight on a much smaller area, move
the same amount of fluid, but actually gain a mechanical advantage. Think
about how much force a ladies high heal shoe can put on a surface. It is all
simple math: force per area. This is one reason it is so important to have
new brake shoes matched (arced) to the actual brake drums. With the small
volume of fluid any Master cylinder moves, you don't need to "use it up"
flexing the brake shoes to get them to contact the drums.
