Why does your car vibrate when your at a stop light or while applying the brakes for a 2001 dodge stratus?

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.

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.


Every now and then the brake lights turn on and the brake pedal is not being depressed whats going on?

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.

Why does the car's electrical turn on when the brake pedal is depressed and the car is not running?

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.
