" You can do some alteration in rear brake action by changing wheel
" cylinders. Finding one that is larger in diameter slows application
" due to taking a larger volume to move a stated distance. Smaller
" cylinders apply faster.

-but-
you generate a certain amount of pressure when you stand on the
brakes.  pressure * area = force...

larger cylinders multiply your force, applying the rear brakes harder.

you want smaller wheel cylinders to weaken the rear brake action.
