A COMMON CAUSE FOR A DROPING BRAKE PEDAL WOULD BE A LEAKING MASTER CYLINDER.(INTERNAL LEAK). THERE ARE OTHER REASONS BUT THAT IS A COMMON ONE. YOU ALSO HAVE AIR IN THE SYSTEM, NO FLUID, OR A LEAK SOMEWHERE IN THE SYSTEM(MAJOR LEAK). IF THE PEDAL JUST FELL TO THE FLOOR TRY LOOKING UNDER THE DASH AND MAKE SURE THAT THE PEDAL DIDN'T COME LOOSE FROM THE PUSH ROD AND NOW IS JUST "HANGING".
What else can I help you with?
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 does it mean when you can press the brake pedal to the floor with ease?
You don't have brake fluid There could be air in the system and it requires bleeding to rid it of air. If the vehicle is an older one, the master cylinder may be porus or the bore pitted. It should be resleeved or replaced. The seals could also be flat. Jam your foot down hard on the brake pedal. Is the pedal high? Does it sink to the floor if you rest your foot lightly on the pedal? www.powerbrakeandsteering.co.za
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.
