I would think silicon would do that, not silicone.

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.

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.

I know of at least three engines ruined by leaky master
cylinders/boosters and this was in Texas.

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.

I noticed in a later post that the poster indicated that it was DOT-4
synthetic... I have no idea what that stuff is make up from. DOT-5 is
the silicone stuff.
So the ball's up in the air again...
