Brake Bumper button is broke , or stuck ... it's the little button under the pedal to the connector to the electrical system ; it's needs to be replaced or it will drain your battery. What I did until I got it fixed was either 1)pull the fuse to the brakes , or 2) just disconnect the battery. I just did 2 in the past week ! I own a 1982 Datsun 280 zx , and a 1987 Nissan 300zx. .
Bad brake switch
Replace Alternator
Probably a brake light switch.
1 of 3 reasons why, your head lights are on, your reflector lights are on ,or your brake sensor is broken

Brake lights could stay on in a 1999 Dodge Stratus because of a short in the wiring. If the headlamps are off and the brake lights are still on, check the wiring for the brake lights that is inside the trunk. Sometimes cargo in the trunk can interfere with the lights.
If the brake lights stay on that probably means the switch on the brake pedal that activates them is defective.
faulty hdlmp switch
check the brake light switch
The brake relay switch is bad.
Adjust the brake switch which is above the brake pedal.
the brake lights are on a separate cuircut,if your brake lights are staying then it will be a fault with the brake light switch. the switch is located under dash,and will be on or very close to brake pedal.
