Hard pedal

Ok so I have a 71 dart with front disks rear drums. Brakes were good when I got it, (I mean pedal normal feel and stopped good). Saw pads were low and MC lid leak, soo decided to do all brakes. First rear shoes and turned drums. Drove car all was good. Pulled it in to do fronts. Needed new rotors, ordered some drilled and slotted. Figured I would replace MC, ordered it. The Mc that was on it had one bigger reservoir than the other. (just figured it was from a later year like 74 or 76ish). My new one came it has the same size reservoirs. I says for disk and drum setup. I have manual brakes. Put it on, new pads, and bleed them. Now the pedal is really hard and it barely stops. The bore of both the new and old are 1.032. And yes I bench Bleed the MC. I had to total collapse all caliper pistons and still had a hard time fitting the new pads, but got them in. Not sure why such bad stopping and hard pedal. Ideas???
