brake light and anti lock light on

i have a 92 b2200 and the brake light and anit lock light keeps coming on everytime i hit the brakes. but then i can hit the pedal again and they go off but as soon as u touch the pedal its back on. the brake fluid is full, but i havent had the time to look at anything else. anyone run into this b4?
thanks for the help

there is a fluid level sensor on the master cylinder, but you said it is full.....it could be going out, or the actual switch on the brake pedal could be going aswell.....then again it could be the anti-lock controller going out.
it is located under the drivers seat, some peeps on here have removed it because of this same type problem, only thing is you won't have anti-locks in the rear anymore......

the is a sensor on the rearend that if you lower it the gastank crossmember will hit it and break it and make the anitlock light come on.
