Right. But if there is no pressure then the pedal will travel w/o resistance. I would blead the lines and the brake would be extremely hard at first. Then (relatively quickly) it would allow more air into the system and reducing resistance on the pedal. I don't claim to be an expert but a friend on another forum (CRSX) explained it to me a while back and as soon as I told him the issue he knew the problem. I replaced it and it was fine
