There are several reasons why your car brake pedal can go to the floor. None of them are good. Your reservoir might be low on brake fluid. Your master cylinder might be worn out. Some of the brake cylinders might be worn out. Whatever it is it is time to get it fixed before you kill someone else and perhaps yourself.
What else can I help you with?

Why does the parking brake pedal go to the floor on a 97 suburban?

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 causes brake pedal to go all the way to the floor on a 1999 Ford Taurus?
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.

What happens when you run out of brake fluid?
The brake pedal will go to the floor but will have absolutely no effect on stopping the vehicle. When you push on the brake pedal it moves the fluid through metal tubes (called brake lines) to force the brake pads against the rotor which slows and stops the car. No fluid means nothing is in there to make the brake pads engage the rotors.
