How's it going guys! soooooo I have a problem with my braking. It is really soft! literally I push the pedal to the floor and it took a few feet before it came to a stop! I've got a new master cylinder put in! properly bench bled it! bled the lines entirely! I'm at a loss for what the problem could be I'm thinking possibly the brake booster but there isn't any leaks on the inside where the pedals are and i don't hear any air anywhere leaking! any help would be greatly appreciated!!

No, it's not possible for a booster to do anything like that, it's part of a straight solid mechanical connection between the pedal & MC, with a little bit of plastic and a little bit of play for its valve to work.
Air compression or something loose/complaint/springy.
