Check for vacuum leak at brake booster
If you are saying it vibrates while applying the brakes just before you come to a stop, then the brake rotors are warped. You will need to have them turned and trued, and replace the front brake pads. If you are saying it vibrates while you are sitting still, then look for a vacuum leak.If you are saying it vibrates while applying the brakes just before you come to a stop, then the brake rotors are warped.

brake switch located on the top of the brake pedal
you still have air in your lines
Bad CV joint? How about a bad steering box?
You may want to start with the brake fuse. If you still have turn signals and lights. you may also want to check the brake electical relay switch in the relay box Check as well the brake switch located at the brake pedal.
If sitting still in your car with the engine running you can apply the brakes and the pedal slowly goes towards the floor you have a defective brake master cylinder. The only repair is to replace the master cylinder. This is a very dangerous situation and must be repaired immediately. Failure to replace the master cylinder may result in an accident.
Sticking Brake LightsI had this very same problem when I owned a Nissan 300zx. There is a switch in front of the brake pedal that when the brake pedal is pressed the metal part of the pedal presses down on a little button which turns the brake lights on when pressing the pedal. What I did was I got under the dash, took a flashlight and put a little piece of tape in between the pedal and the switch. It acted as a cushion because the pedal wasn't pushing down on the switch as it was pushing on the tape and when I pressed on the pedal the lights would come on but the tape pushed the pedal back to shut the switch off. If you want to avoid all this consider having your brake pedal adjusted. If your brake lights come on still consider having your cars wiring checked out.
faulty brake light switch (on pedal)
It turns the rear brake lights on as a safety feature. The brake pedal is pushed in, causing the fluid to move forward in the brake cylinder,activating a brake light switch. Even if the vehicle is off, the lights will still come on.
it sounds like to me that your master cylinder might be bad
the brake switch at the pedal is stuck or out of adjustment.
There are a number of reasons this could happen improper seating of the pads/shoes or air in the brake line
