E-Brake light coming on during WOT
 

Hey guys I noticed the other day that when I got on my car a bit to redline the E brake light comes on every time now! I just replaced my old optima red top which was beyond shot, and I don't recall it doing it before so I'm not sure if it is related. The same day i replaced the battery for some odd reason the radio stations wouldn't come in, and had a high pitch wining noise that increased with engine rpms. It hasn't done that since though.... I've had the service tcs/abs problem for awhile now since i replaced the front right hub bearing and sensor shortly after, hoped it was just the bad battery but that was confirmed to not be the source of problem. Anyways here's a quick video of me punching it and the light popping on, I've never heard of this issue before! Sorry for lack of traction and a little limiter.:leaving:

Wasn't able to watch vid. Is your brake fluid low?

that is what I was thinking, low brake fluid. Also wasnt able to see video...

The switch for the light is under the boot and is a simple piece of brass that hits ground when the handle is lifted. It sounds like the switch is loose or adjusted too close to the handle. If my memory is right, if you lift the boot you should see the switch.
