It's one of two things, first when you changed the pads did you open the bleeder BEFORE you retracted the piston? If not you may have blown a seal in the master, second, after you change front pads, you need to pump the pedal up until the pads actually contact the rotors...?

If somehow you got air into the brake pressure modulator valve, you need the Tech II scan tool to bleed it out...
