Take this with a grain of salt...I am thinking the primary chamber on the m/c, (the one closest to the pushrod) should be for the rear brakes on your trike. (on a car this may be reversed? Then the front brake be adjusted with the proportioning valve. to balance the braking with regard to the final weight distribution.
I have not tried this myself...one trike of mine has a mechanical brake up front, the other has a separate m/c for both front and rear.
So food for thought only...
You are 100% correct with the chambers of the Master, I would be thinking of a adjustable residual check valve for the rear brakes
