Hey guys, i converted over to vacuum brakes today. now the only working brake light is the top one. you push the brake and it lights up, the bottem left and right do not work. any thoughts or suggestions.

Probably has something to do with the switch that makes contact with the brake pedal. You changed the pedal, right? Check it with a test light.

Now that I think about it, you must have power there because your third brake light is working. Will your hazard switch light the brake lights?

There are two contacts within the brake switch assembly, one runs the 3rd brake light up top, the other contact runs the other lamps. You either knocked the wire off the switch assembly or it isn't releasing enough with the pedal to operate. May need adjusting.

Or you broke the switch assembly.

Trace the white wire off the brake switch as I think it goes into a connector on the steering column that can also cause intermittant contact and problems.

White wire runs the lamps you need to get working.
