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.

Did you bench-bleed the new master cylinder before installing it?

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
