I changed my pads and discovered that my calipers were leaking so I replaced them. After replacing calipers I bled the system but I had no brakes. I replaced the master cylinder and bled the system, still no brakes.

DO YOU HAVE A HARD PEDAL?

DO YOU GET HARD PEDAL AND DROPS AS YOU BLEED THE FRONT CALIPERS---THEN "RECOVERS" TO FULL PEDAL WHEN BLEEDERS ARE CLOSED AND A FEW PUMPS ARE PERFORMED?

THIS IS SORTA PUZZLING--PLEASE ANSWER AND ADD ANYTHING ELSE THAT COULD BE RELEVANT

When bleeding the front brake after several pumps the pedal was hard but when the bleed screw was opened the pedal did not move but fluid came out of the bleed screw.
