pressure x Area = F
Extremely high pressure (as in small Area) would cause glazing, overheating and other bad effects.


I know I have to work on my communication skilzzz

I am sure a lot of research went into the size and shape of the pad. heat dissipation, gas removal, chip resistance... all those issues are essential.

while we are on the subject of size, notice how Todd recommends small piston diameter in this thread where as from the stopping power considerations we would like to have it as big as possible. this just goes on to show that simple mechanics 101 considerations have very little to do w/ actual product. nevertheless, understanding of mechanics 101 is an essential step.



A large piston would require lots of pedal deflection to achieve the same force applied to the rotor.
