Check brake system....
I can go days with out the warning coming up or it can happen couple times a day but either way all the lighting shuts off in the cab and the the Heads up display (if thats what you call it) says check braking system. It will only say that for about a second and a half then goes off, and then I usually run the system check function and it says "Brake system ok". I have already made sure that the that the fluid is topped off and the ABS functions properly when the light comes up. Also sometimes it will flash a message so fast that the only thing I can make out is it's saying something about the brake fluid. Could there be water contaminating the fluid? 1300 miles on the truck.... Oh also it seems to happen when Ive been bouncing down ruff roads or plowing through snow.
thanks for the help
