David, Would you agree that all the parts being metal would not be hurt by Dot5. Would you agree that Teflon SS hose would also not the affected by Dot 5. And would you agree that since I build brand new seals that aren't affected by Silicone Dot 5 fluid, then my question is why have you been saying for years, don't use DOT 5. What in your book is going to be hurt by using DOT.

The type of brake fluid will have no effect on the "stiffness" of the clutch. As far as a hydraulic system is concerned as long as the fluid is not compressable (and all of the air is removed so it is a true hydraulic and not pneumatic system) you could have water in there. I do not recommend water because it's boiling point is too low and it will corrode the metal parts. I also do not recommed silicone (DOT 5). Use Castrol GTLMA DOT 4 and change it every other year. Same for the brakes.
