Hy Jason49er, did you bench bleed the new master cylinder before you installed it? It sounds to me like you have put enough fluid through your system, that you should have at least as good a pedal as your overhauled master cylinder gave you. Are your brakes adjusted up properly? I think by your description of what you have done that maybe the "new" master cylinder might have a problem. Make sure your brakes are adjusted up, and bleed carefully one more time, if they are no better I'd return the master cylinder to the seller.
