It's the 2ton 57 GMC LCF Every thing new in the brake system. Had to pull one of the rear hubs to stop a line leak. Now after bleeding good, still got great brakes, but the brake lights stay on real-real dim.
It has a new brake light switch that is installed in a tee in the brake line. Was working fine before.
I do seem to have the right rear brake drum adjusted up a little too tight.
I can unplug one of the wires to the switch and the lights go out.
1. Would the adjustment cause this?
2. Has my new switch gone bad?
