Stop driving your car asap.It means there is a brake fluid leak.Get your car towed to a mechanic.
Usually in every vehicle the brake lights come on when the brake pedal is pushed in. There is a switch connected to the pedal in some way to make the light switch on.
Worn master cylinder.
If nothing is holding the pedal down then the brake light switch is at fault.
This is because of the antilock brake systems, or ABS. When the ABS is activated in a vehicle it can feel like the pedal is pushing back at you when you stop or start to slowly press the brakes.
Sounds like the power brake booster is bad. Get it checked out.
Look under the dash on the driver's side, half way down the brake pedal. When you depress the brake pedal, the pedal moves away from this switch, which allows the brake light pedal circuit to complete, and your brake lights come on. This brake light switch is always hot/on, as required by federal law, so that even with no key in the ignition, if you hit your brake pedal, the brake lights will come on.
Check the switch adjustment on the brake pedal arm.
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.
it wont just come out. you need to pump the brake pedal.
Check rear bulbs, rear brake bulb fuse, and check the swith on the brake pedal.
you probally need to replace the bulbs
If you step on the brake pedal , yes
