Hey guys, about three weeks back I was driving along and had the 'BRAKE' light come on and then went off within less than a second. I was thinking that I might have imagined it at first being that I was a little tired of work that day and it's the same light that is on when the parking brake is engaged as well. Then about a week later I was speeding up quickly from a stop sign and it happened again, this time it was on for roughly two seconds and went right back off again. I checked the fluid level in the reservoir and it's halfway between full and minimum so it doesn't seem to be a fluid level issue and the level wasn't perceptively lower than it was about a month ago when I checked it last. I then disconnected the parking brake switch wires to see if it would come on again while driving and after awhile it did, this time it was after slowing down about a second after I released the brake pedal while entering a turn in an intersection. I reconnected the parking brake switch since I had eliminated that issue.
What would cause the light to come on intermittently other than fluid level or the parking brake. I don't have a low pedal. The pedal doesn't sink at all over time if I sit on it at a stop sign for a few minutes, which would indicate an master cylinder internal leak. Since the brake fluid level hasn't gone down it isn't leaking out from a caliper.
I'm not sure what could be going on to cause this light to come on, it's come on about six times now, never at idle. It's come on twice near red line while accelerating, once in a turn, another time just randomly while driving at a constant speed on a level road driving straight, once immediately after getting off of the brake and one other time that I don't remember what the conditions were.
Where are the sensors that turn this light on, are they all in the master cylinder itself? Again, the brakes seem to be performing normally, if I stomp on them they act like any standard non-ABS car and lock up the tires as it always has.
What could this be?
