Buick Century '93 brakes light will not go off

Please, help. Here is my problem: After the brake pedal released, brakes light is still on. This happened occasionally, not on a regular basis. Some times it helps when I push brake pedals several times.
Thank you.

Do you have anti-skid braking? If not have you checked your brake fluid level? If it is low (or was too low and you added fluid) you may have air in the system which causes an unequal pressure which will turn on that light. You'll have to bleed the brake system to get the air out.
In an ASB system there are several possibilities to cause the light depending on the system. Better buy a service manual or take it to a specialist.

Brake light in the dash? Brake lights on the back of the car? If it is the ones on the back of the car. Replace the brake light switch. It is a cheap and easy repair. If is the one in the dash the previous post covers that.

Thanks bignoisey, thanks public. That is the lights on the back of the car. I found the switch wich turns on this light (correct name is a "stop lights"). It is located under the brakes pedal and pushed it several times in and out. That fixed a problem, at list for now. The location of the switch is really uncofortable, so as long as I can do this quick fix, I will keep the old one.
Thanks a lot again for your help.
Regards...

You are more than welcome. Glad to hear the good news.
