The rest of the time it worked well. As I don’t want to be caught without a clutch at a later date I am changing the clutch master cylinder. I have received a replacement and am preparing to install it.

I have used silicon fluid for well over 10 tears and never experienced any problems with it and have never seen or heard of this type of warning before. I have never heard of any destructive qualities of Silicon fluid.
