Parking Break Light

My parking brake light comes on and off. This may be a simple fix or not I have no idea. The light comes on when I accelerate or make left turns believe it or not it doesnt come on when I make right hand turns whats up here? I have been monitoring this for a few days to see when and what causes it to come on. It also comes on when I start up a fairly steep grade.

buddy i had this same problem. mine done it on
steep hills and sharp turns. check your brake
fluid, even if its a little bit low, top it off
it fixed mine. i thought that the cable wasnt
rolling up i put wd 40 on it and everything,
but it was the brake fluid...let me know if
that fixs it ..........tacoma man.

Ok thanks I thought of that, I did check the fluid and it wasnt at max but then it wasnt below the min mark either the last time I looked.

mine was like that too but i topped it off and
it hasnt come back on since
