I have not done the conversion to dot-5 on any of my projects. Still using dot-4. I think that most of the trouble with breaking systems on spits is because fluids are not changed on a regualr basis. I believe dot 4 replacement is recommended every 2-4 years. I have a 76 rolling restoratoin that I just bled 2 pints of dot 4 through to flush it out and have been driving it for 3 years now with no trouble.
Since dot 5 is sinicone based, it will not absorb any moisture at all. I think cleaning the system out with shop air would be suficient. I would use a can of dry air to evacuate the system after using shop air. (Air Horn can). You might be able to use the dry gas compound from an auto store. I think that stuff that you want is anhydrous alchol. That is pure alchol with no water in it. Denatured alchol is ethyl alchol that has a compound in it that will make you sick if you drink it. It does not mean that it is not mixed with water. I think you can go to a drug store and ask for anhydrous methyl alchol. ----- Original Message ----- From: "Geoff Heyland" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, December 17, 2002 8:27 PM Subject: "Denatured Alcohol" and Flying Fantasies > OK folks - I've seen several references to denatured alcohol as a recommended > brake/clutch system cleaner prior to switching to DOT 5 fluid.
