Given that the front calipers usually have more and larger pistons than the rears, they need more fluid. Hence the balance bar in the original post - adjusts bias front and rear.

I have that Valspeed MC setup on my car. I considered something similar for when I added hydroboost power brakes to my '65 Land-Rover but decided to go to a balance valve instead - a little easier to adjust. (The valve is in front of the remote reservoirs.)

Not sure of how that setup works, but for the Tilton underfoot pedal assembly I have, one MC goes to the front brakes, and the other MC goes to the rear brakes. For example, i cannot open a single front caliper bleed screw because I'm still pushing against the rear calipers. This is why I said to bleed a side at a time. Tilton outlines this fairly well.

That is how the Valspeed and all other systems I have designed/set up work and is how most systems work*. MC1 pushes RF and LF calipers. MC2 pushes RR and LR calipers.

I think we are saying the same thing; if not my bad.

* I have heard of some doing diagonal, e.g., R front and L rear. That would give some VERY wonky handling if one diagonal circuit failed in the middle of a turn. Or even driving in a straight line. But that would still bleed ok.
