when completed make sure the pedal travel matches the master cylinder travel. the full pedal stroke should equal or slightly exceed the pushrod stroke required to bottom the master cylinder. also ensure there is some slack in the pedal so the master cylinder is allowed to fully retract back to the resting position, otherwise the brakes can be slightly applied and cannot recieve more fluid to the cylinder as the brakes wear or the fluid heats/expands or cools/contracts. the heat/expand is the one you will have trouble with right away because the brakes end up not releasing when they get hot. ensure the spring on the pedal return is strong enough to fully retract the pedal.
I know, you have this figured out. some other readers may get a tip from it though.
have fun, post pics. we all love the pics, especially of a classy looking project like this one.
