Ok, so I got a liter of ATE Typ 200 and used about half of it to flush out all the DOT 5 fluid from the clutch hydraulics. What a PITA! Since the DOT5 silicone is less dense than the DOT4, the DOT 5 would sit on top of the DOT 4, thus all the DOT4 was bleeding out before the DOT 5... I had to vacuum out all the fluid until the clutch system was empty. I put in some DOT 4 and vacuumed it out until there was no trace of DOT 5 left in the catch can. Used about 1/2 a liter to do the flush, then filled the system with DOT 4 using the typical bleeding process.
Clutch feels great! I read many people saying that the silicon DOT 5 is bad for seals and when it is mixed with DOT 4 is create a goo, or sludge. I do not think this is true. The silicone is inert and should have zero effect on seals. Also, I mixed the DOT 5 and DOT 4 together in the catch can. They didn't not interact at all. It was like oil and water. Even over several days.
