The car a is a 95 E250 Diesel S124, 500k km. I think shoes are worn and should be replaced because the pedal almost goes to the floor but i also think the pedal mechanism doesn't work as it should. The pedal is dangling and not fully returning when releasing the parking brake. To me it feels like a spring or something is missing somewhere. I can only make the parking brake light go away by very slightly lifting the pedal with my left foot. Thanks
