Front Master Cylinder milky residue (F650GSK72 -- anyone know how to flush/fix it
- Thread starter cujof16
- Start date
Hi Cujo - Welcome to the forum.
You don't say how old you bike is, but when was the last time that the brake fluid was bled? It appears that it's part of the 12k service?
You may have seen this already, but here's a good video of how to bleed both front and back brake systems. Someone more mechanically apt may come along, but I would start by using a turkey baster/straw with your finger on it to remove as much of the milky fluid as possible, then flush the whole system, double check that the brake system works, go for some rides (gently activating the ABS system too), then do another flush. GS twins are still pretty new, and if they were maintained, shouldn't need a rebuild yet.
Good luck!

Same issue
Hi Cujo,
I had the same issue my 2015 BMW F800Z with 3000 miles on it. I took it to BMW of Palm Bay this past Wednesday and they charged me $115 to bleed and flush my braking system. The master cylinder did not have to be replaced. If left untreated, the service department advised it could effect the braking system. I know this doesn't answer your question on how to do this procedure yourself, however, you will have a point of reference if you decide to let the dealer do it.

I see this regularly on newer bikes that come in for service. So far it does not seem to be linked to any lasting problem, although one or two bikes had a slightly gritty feel to the MC action when bleeding them.
