    Have a 2006 Peterbilt 357 and the drivers front turn signal comes on when pressing the brake. Grounds are all clean. Going to try a new stop lamp switch. Any other ideas?

    Doesn't the tractor brake lights go through the turn signals? Maybe check there.

    Checked the back signals and they work fine. It's just the front drivers signal that comes on. Don't think it could be the signal lever? Signals work fine. Just when braking the signal light and dash indicator come on solid. Brake lights work like they should. Does this with or without a trailer.
