Everything works as it should except when I have my lights on and hit the brakes. When the lights are on, it works but as soon as I hit the brakes the light go out instead of get brighter. Turn signal work as they should.

I hook up the tailer to my other truck and all is good.

So, where is the short on my truck. Its a full size chev. 1992.

I think thats a ground problem

[stupid] Sounds like a bad ground to me, or the wire for the brake lights has rubed through and is grounding/shorting out.

I'm with Liz, ground is probably rusted up badly on truck frame. Supply another ground from trailer to the truck and you'll solve the problem.
