Terry, In my experience with brake switches with silicone fluid: 1. The brake lights DON'T work when stepping on pedal. I've never had them stick ON. 2. The switch will not work again even if cleaned. Don't think refilling MC with regular brake fluid and leaving the rest of the system silicone would be recommended. ie; One likes water and the other doesn't, so it would be a battle of the hygroscopics and the hydrophobics. Since your lights are sticking on, could it be the piston in the MC is not moving backwards and releasing pressure fully on the whole system. Got brake drag and a low pedal after initial push?

Noticed the note last eve which mentioned shorting of switch as a result of silicone fluid and bet that is my problem. This is my only 55 with silicone darn it. Lots of others without it at least. I remember the discussion--just enough to be dangerous. Can the switch be removed and cleaned or does it need replaced? I suppose I need to replace the silicone fluid than also or take a chance and wait till it goes bad again? Can I just refill the master cylinder with regular fluid and leave the silicon in the wheel cylinders? Thanks for guidance in advance.
