Bob,

What I said was that by going to a larger caliper the brakes should not work better than before you changed them. The amount of fluid needed to fill and thus move a larger caliper piston would be more than before your swap. Thus the brakes should have felt better before the swap not after.
You can pinch off the brake hoses one by one to see when the pedal gets firm. I have seen some flex hoses swell and that will give a soft pedal but I would figure you have new hoses on the car you are building.
