Parking Brake Lamp

Alright ya'll, I live in a town in Oregon called Pendleton. Now, going up Dead Man's Pass to La Grande is pretty cool, got some nice corners up there to have a bit of fun on (in safe measure, of course). Every time I take a 45mph corner at about 55 or 60, where the truck starts to pull a little bit, the parking brake lamp comes on. The brake is fully released, and there's a full tank of fluid under the hood. any ideas?

 

Possessed.

 

Check and readjust the cable. Could be sticking just enough to mess with it. I sometimes have to jiggle the hand after it's released to get the light to turn off.

 

^ that or the actual cable itself is loose on your rear axle, possibly about to break. Have you followed the parking brake cable from lever all the way to the actual brake?

I have not, no clue where to even start. Sometimes it does it when I leave my driveway and like 45acp i jiggle the handle and it shuts off. It's just odd when I'm taking the corners that it comes on, I had a civic that did the same thing when fluid was low, so that's what i first thought.
