Erroneous? Nice! :thumbup:
But Unless something has changed, DOT 5 has never, and will never be able to be used on a DOT 3 or 4 system without some extensive work. They can be mixed but need workto be switched just for the heck of it. DOT 5 brake fluid does have a higher boiling point yes, but besides that, there are very little positive reasons to use it. On a DOT 3 or 4 system, if rubber seals wear or detieriorate (sp?) the fluid is absorbed into the rubber, which causes it to expand. Preventing leaks. DOT 5 DOES NOT have that characteristic. They are more prone to air leaks and such.
To switch a system PROPERLY, you have to rebuild/replace you MC, and ALL Seals in the system. That includes wheel cylinders if applicable or piston seals.
Unless you are doing some SERIOUS racing, this is a totally unneccessary "upgrade". Maybe GRANT will chime in and enlighten us with what fluid they run.
Like I said, unles something groundbreaking has RECENTLY come out, DOT 5 IS NOT interchangable with DOT3 or 4. This is kinda the jist of it, most is on the DOT!
If I am misimformed, I will stand corrected. Until then, SPOBI! ( I always wanted to use that)
