All you need to bleed the brakes is a friend and doing it old school style.
Replace the calipar, fill the reservior, then starting with the new calipar just have them push down on the pedal -you loosen and bleed, tighten screw, they let up, then push down again, -you lossen / bleed, repeat at all 4 corners until you have clear brake fluid bleeding out at all 4 corners.
Once you have done that see if the pedal feels right to you after the pads and rotors have had a chance to seat properly. If the pedal still feels spongy then go onto a dirt road and get into the ABS a few times. Then go re-bleed the brakes again.
