FWIW, dunno if it helps you feel better but, I change the fluid in my race bike after every race meeting. It's cheap after all - not suggesting you do that but once every 6 months is a good measure for keep everything tip top.

Some great info on this thread.Keep it up fellas.

That is a good tip, but I would not leave the reservoir cap off overnight. That would allow moisture in the air to be absorbed into your brake fluid. :)
