Dave,

Thanks for the silicone fluid info. Originally I was planing to use silicone because it doesn't damage the paint, I still may but I figure the more info one has, the better the final decision. My brake system is new and never has had fluid in it so that shouldn't be a problem. To convert from silicone to conventional I assume the system must be flushed.

Thanks again.

Mike,
Just a few words of advice - assuming that you have new wheel cylinders or calipers and a new master cylinder - they were assembled at some supplier using brake fluid or a compatible material as a lubricant and protectant. It is not compatible with silicone. Every freakin' rubber piece - seals, cups, valves - anything with rubber must be replaced with new and DRY pieces before you install silicone brake fluid. Use the silicone fluid then for your assembly lubricant. The MC and WC should then be bench cleaned with alcohol. Been there,........ and it is a PITA. But with that said, if that is the way you decide to go, do it - the stuff does work, but IMHO, not worth the additional bucks and effort. If you decide to change back to conventional fluid, you start all over again with the system clean up.

Dave,

That settles it, I'll go conventional... I'll just have to be extra careful so not damage my way too expensive paint job.

Thanks
