Rear disk conversion issue

I replaced the MC, readjusted the booster pin and I think the rear brake drag is fixed. I road tested and they lock up and release. My temperature gun and hand says no dragging. I have isolated the low pedal to the front, if my troubleshooting method is correct... MC was bench bled. I then attached the rear line which was previously bled with the power bleeder. Plugged the front. The brakes were high and hard. I put the front line on and they go almost to the floor. No leaks and everything nearly new. I bled the fronts old school with a bottle and helper. Truck leveled per MC. Plenty of fluid through bleeders and some air where I repositioned the banjos. I'm lost now.... if the pedal ratio is off, I think it still would have hard brakes. The MC is 1 1/8 which should be enough to get a hard pedal. Should I clamp the front calipers off at the same time, check pedal? Just looking for some suggestions. Craig
