Preety good time back there was few post on multiple master cylinders on car. Do not rmemeber rule was on how to plumb or if allowed.

Would like to un a smalle calipe fo dad bake off hand brake. With Zoomiers off and on throttle is very easy to pick up no matter position car to car. Figure with small single piston caliper would be harder to over apply brakes and with fed you do not want to do that.
