Rear brakes problem

Hello, I recently replaced my rear brake calipers and right rear brake hose (was in a time crunch and the left rear hose was a dealer only item that couldn't be delivered for 3 days) and am having a problem getting the brakes back the way they were before I started messing with them. I am having a real hard time getting a good firm pedal. There is no indicator light on the dash that is lighting up.

First we gravity bled the rear brakes and then we bled the brakes in the order right rear, left rear, right front, left front.

We replaced the rear calipers because the right rear was locking up. We first noticed this when the car had a really strong smell and felt that the right rear wheelwell was extremely hot. I then took the car in to get checked out at a local brake shop and they quoted me an outrageous $750 to replace the rear calipers and hoses. When they took of and replaced the pads that the right rear had significant wear and that it appeared the right rear was the only one with problems.

Yes, the fluid does squirt out of the rear bleeder valves just like the front. We did keep fluid in the master cylinder all the while. Do you have any idea why when we were bleeding the rears that the pedal wouldn't go all the way to the floor like it did on the fronts? I'm so confused.

Let me know if there is any more info you need. Thanks!
