No, a busted brake booster will not cause the brake pedal to go to the floor. It will however cause the brake pedal to be extremely hard to push. A defective master cylinder will cause what you describe. Replace the master cylinder and bleed the brakes.
It can because it happened to me. The booster lost vaccum and the pedal went to the floor.
Sorry, you are wrong. The only reason the pedal went to the floor was because the master cylinder failed. The brake booster only boosts the pressure on the master cylinder and allows you to not have to push so hard on the brake pedal. Cars of yesteryear did not even have a brake booster and they stopped just fine albeit you had to push the pedal allot harder than with power brakes. A failing brake booster will not cause your pedal to go to the floor although it might cause it to go lower than normal before the brakes apply. As long as the master cylinder is good you will still have brakes, but you will have to really push hard and might even have to pump them up in order for them to stop the car.

The first suspect when a brake pedal goes all the way to the floor is an empty - or almost empty - master cylinder. It could also be a bad brake booster, a ruptured line, etc. The car should be TOWED to a repair facility, and the cause found and corrected before the car is driven again.

sounds like you have a leak in your Brake Boost Controler, you should also check to see if there is any leaks in the vacuum lines that connect the engine to the brake booster.
