i would get a brake pressure guage, and see how much you get at the calipers. usually 900 to a 1000 max should do. i'll bet now your in about the 400 range? if you want send me a pm with some info on the calipers ,master cyl.bore size ,and current pedal ratio, and i'll try to get you sorted out.

Thanks Mark. I'll get that info together and send it to you
