I have always had to pull up on the pedal when stopping so my lights wouldn't stay on. Doen't help anymore. I see no spring and I think that is in the master cylinder anyway. I have seen threads recommending adjustment but I can't find anything on how to do it. The switch was only 11 bucks and mine looks like it may be broken so I figure I'll replace it anyway but I can't figure out how to replace it or how to adjust it... I have a 1968 Newport with non-power drum brakes.
