Next time, screw the ABS System...you're getting too complicated. First off, the post of calipers being upside down is a valid one. When replacing the caliper, make sure the bleeder screws are at the tops of the calipers. Gravity bleeding is the next step by opening all four of your bleeder screws until they're dripping pure brake fluid and as each one drips with no problems, lock the bleeder down until all the bleeders are dripping normally while watching the master cylinder level. One thing I didn't read above is whether your new brake pads were seated against the rotors or not. That will cause a "dead" pedal as well even though the brake system is without air.
Since I work alone, I bought a pressure bleeder for my '87 BMW convertible to change the brake fluid out once a year. I got it through Bavarian Auto.com.
Now that your brakes are working, you need to find out what caused the caliper to lock up. Brake fluid, albeit DOT 3 or DOT 4, absorbs all the moisture in the air and that's where rust and contaminants enter your braking system. Find out from your Dealership as to whether they re-bled the system with a pressure bleeder or just used your brake fluid. Your brake fluid just being open to the air will absorb any type of humidity in the air and one day this problem may occur again from contaminants inadvertently put into your system. The pressure bleeder I have is a "closed" unit, so no air or contaminants get into it.
The Piston within the calipers of long ago were made of steel causing caliper lock-up. Whenever I had a vehicle come to me and had to over-haul the caliper, the new caliper overhaul kit came with Bakelite pistons or hard corps resin instead of metal to prevent rust formation at the piston and caliper with the 3 seals to keep it all together.
Sorry if this makes no sense to you...I'm on my 1st cup of coffee.
