2004 Chevy hd right turn single comes on when brakes applied?

I have a 2004 Chevrolet 2500 HD 4x4. The fuse was out and caused my right brake light to not work, I found the fuse replaced it. Now when I hit the brakes my right turn signal comes on in the front back and on the dash. But it works if I use the right turn signal and then hit the brake. Please help me!!
