wormhole

Okay, last night when doing some off-roading I noticed that when I would go up a steep incline that my brake line would come on. I didn't think much of it at the time thinking that it was a spoof. Well, on my way to work today I noticed again that it came on when I was on a step incline (stopped at a red light).

Would anyone know what might be causing it? I just trying to solve a problem before it becomes a major one.
