The brake pedal goes to the floor and they act as if they're pulsating?

Sounds like a bad booster. If you can't pump up the brakes to get a firm pedal while engine on, you might want to have it checked.
If they're ABS brakes and you hold the pedal firmly, it should feel like they're pulsating but the pedal shouldn't just go to the floor. Could be the master cylinder.

On a 1987 Honda Accord why would the brake pedal vibrate when you press the it at 35 mph if you have replaced the rotors three times and it did not help?
AnswerUsually a pulsating brake pedal is an indication of a warped rotor. When you replaced the rotors did you torque the lug nuts to the proper specs, (80 ft lbs)? If not then you are warping them each time. Also make sure you tighten in a criss cross pattern. Of course you need to check each and every rotor for trueness. Also a warped wheel can cause this. Check all your wheels for a bent condition.If your brake pedal is pulsating. You might have a out of round rear brake drum. When your front rotors are warped you will feel it in your steering wheel. Try this test. lightly rest your foot on the brake pedal, with your foot resting on the pedal slowly apply your E brake. ( your E brake only works your rear brakes) If your brake pedal pulsates the problem is in the rear brakes.
Identify four common disc brake problems.?
A warped rotor causing a pulsating brake pedal is probably number one on the list.In my neck of the woods, rust is another issue. Even with daily usage the rust builds up on the braking surface of the rotor again causing a pulsation in the brake pedal.
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.
Why do the brake lights on a 1992 Mustang only come on when the brake pedal is pushed all the way to the floor?
The brake light switch is out of alligment. Check on the brake pedal arm and readjust the switch.
How do you know if the master cylinder is going out?
The brake pedal will sink to the floor when applied and the brake fluid reservoir remains full.
