Hey all,

My clutch slave cylinder is going and I bought some Dot 5 fluid to replace the old stuff. I like the idea of not having paint ruined from a potential leak. The whole bottom of my 1200 has paint coming off because of the leak. I am now thinking there could be possible problems with using Dot 5 (corrosion resistance, etc.) Has anyone tried the Dot 5 in their goldwing?

Thanks
Davebave

Dot 5 is okay to use in the clutch system. Don't bother using it in the brake system though as it's not really needed in a Goldwing. More suitable for high stress systems that fade.

Sounds like potential confusion having two different hydraulic fluids in one bike. They probably are cross compatible but just seems complicated for no gain.

I actually was planning on switching completely (brakes and clutch), but think I may have changed my mind. Although, the Dot 5.1 sounds pretty nice.

Davebrave, I can't specifically tell you about how your Wing will handle Dot 5 fluid but I run a high performance Brembo brake system on a different type of vehicle & was having some brake loss & fading due to boiling fluid after a few 140+ mph stops so called Brembo & talked directly with one of their brake engineers. Iwas told point blank not to use a Dot 5 fluid in a Dot 4 designed system.. He said that even with a good flush of the system there is a good possibility of an incompatibility issue but even if that wasn't an issue the inner rubber components could be a future problem due to not being designed & tested for Dot 5 usage.. He wouldn't outright say that Dot 5.1 would work buthinted it had a better chance of not causing any future problems.
