Braking
Rule of thumb is 75% F and 25%R. The goal is to get the bias at 75% braking power to the front and 25% braking power to the rear.
Interesting previous post regarding the "smaller the hole the greater the pressure" postulation. This is true as can be. If that is the case and if we want more braking effort to the front, then we have to ask ourselves the following. In order to achieve greater braking effort to the front do we need more pressure or more volume?
Does the bore size affect the pressure coming out of the master cylinder? It probably does but I doubt that it affects the volume. If the outlet piping feeding the system is the same size, what is the effect of using a 3/4" as opposed to a 7/8" bore? Will the size of the bore affect the bias as much as it will affect the pressure required to be applied at the pedal?
I would think that an easy solution, allowing us to forego all the mind-bending physics, would be to use two identical master cylinders; equal in reservoir size and bore and adjust the front vs. rear bias using a balance bar pedal setup.
Make it stop on command! That is the goal!
