Long shot, but are the calipers mounted correctly? Most will fit on either side, but bleeders need to be at the top to get all the air out. If it worked before and you did not change anything then probably ok. I agree with others, pedal going to the floor is faulty MC or air in the system. I went thru two large bottles of fluid to get mine bleed correctly after installing all new lines and MC. Also I am on MC #3 from sitting and got being exercised to keep the seals from shrinking.
