1991 chevy caprice 305 tbi
The dash warning light for 'brake' suddenly came on about a week ago, and since I don't have a manual handy i'm not sure which different things this can mean... I had it turn on in the past which turned out to just be to let me know the bulb was out for the rear brake lights/went back off. But this time the bulbs seem to be just fine. I checked master cylinder fluid level - that also seems to be fine.
What else might it be or should I check? What might trip the warning sensor?
