Hi,

If the brake pedal is going to the floor, chances are the master cylinder is bad. When you bleed them, does the brake fluid come out?

Let me know. Also, take a look at this link and let me know as much as you can. For example, why was the booster replaced? Was it leaking vacuum?

Let me know.
