Brakes: Replaced rear calipers, beld them, still spongy pedal

I replaced my brakes all around including the rear caliper since they were frozen and the rubber on them was gone. I bled the system and used 4 bottles of brake fluid. I now have new fluid through the system, but The pedal is very spongey and goes to the floor. It returns very slow to normal position and the abs and brake lights are on. Can't figure it out. I was told that the system has to be reset with a computer, but have no idea where to go from here. the brakes only work when pedal is to the floor and barely grabs. Any ideas?

You have to give us some information on the truck or vehicle. Year, model, make size of engine and trans type the more information you give us the easier it is to give you the exact fix.
If you pushed the calipers back without removing the brake hose you could have damaged the ABS unit. you also could have a bad brake booster, that is my first choice, for the problem.

I have never heard of a computer able to assist in bleeding. BUT I have been wrong before.
