As some of you know, I've made a twin engine shadow.
To get the brakes working, I used the factory (disc/drum) 1988 master cylinder, using one port from the master going to a tee then to each front wheel (factory 1 pin calipers) The other master cylinder port goes to a manual proportioning valve, then out back to a tee and to each rear caliper (also 1988 1 pin caliper design.)
I'm starting to feel like I need a little more volume to get this all working because the pedal is a little low. Not scary low, just lower than I wanted.
What are my options for a larger bore master cylinder with 2 discharge ports?
