I have just discovered that one of my cars which I thought had Dot 3 or 4 actually has silicone and last month I topped off the master cylinder with Dot 4. I am sure I am not the first to do that so what is the prognosis? I can syphon off what is in the master cylinder but by now all sorts of mixing action has occurred.
