Well, I drove a rather long steep driveway tonight..and it flashed again...stayed on for a bit actually. So, I checked the MC on the hill - I am pretty sure it is the sensor on the MC cap that is setting off the light, because the fluid level was very very low on the incline. On flat ground the fluid level is about 1.5 inches below the "Max fill" line on the side of the MC.
My rear brake pads are almost nonexistant - which I am fixing this week along with installing speed bleeders and new front brake hoses. So, I guess the light is telling me to put fluid in it which will happen when I have the system all apart.
