Most likely you do not have anti-lock brakes in your vehicle. Other possible answer is that your anti-lock brakes are malfunctioning. If you have anti-lock brakes you should see a mechanic as soon as possible.

Can the brake booster cause your brake pedal to go to the floor?
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.
What would cause the brake pedal to vibrate hard with noise when braking on a Rover 414i and how can you fix it?

How do you check a hydraulic brake servo?
With the engine off, press hard on the brake pedal. Turn the engine on and the pedal should depress slightly but no more than an inch or two. If your brakes either drag or stick on, or sometimes the pedal goes real hard under foot it means your servo is shot!
