I didn't catch the first part of this thread, but when you mix silicone brake fluid wiht glycol fluid, you get a grey slime. I generally see it in systems that have been drained, but not flushed, then DOT 5 silicone added. The silicone reacts with the glycol. Personally, I don't understand this since silicone is about as inert a substance as exists in the universe. Texas Parts Guy |

I have never known brake fluid to get into an engine from a defective master cylinder or booster. It would have to be leeking fast out the back of the MC, and the booster would take a great deal of fluid - more than the brake system holds - to reach the check valve leading to the hose to the manifold.

Re: Is Synthetic Brake fluid OK to use??
What the guy meant is to use Valvoline Synthetic DOT 4 Fluid. And I believe
other brands are out there. This is not DOT 5. I used it without any negative effect. Does it make stop faster? Don't know, I bleed my brakes every other year.
