Re: 09 brake fluid reservoir
Actooly there are FOUR reservoirs. One on the handle bar and the little one under the seat both are for the control circuits and that fluid goes no farther than the ABS unit. That is why it is so small. The two wheel circuit reservoirs are built into the ABS unit and that fluid goes from the ABS unit to the the respective calipers (rectangular black item in the photo).
You need a funnel and a stopper to flush the wheel circuits since the reservoirs are black plastic and you cannot see the level. Beemer Boneyard sells a nice set up that screws right into the reservoir cap holes. Or you can make your own. Look in the files section under technical for a good explanation of the flush process but it was written by Mark Nebelett for the early Integral brakes that had the reservoirs for the wheel circuits back where your little rear one is. Then look at the addendum for 05's for a bit more info. I agree that it is probably too early to flush unless you have had her on the road for a year on the wheel circuits and two years on the control.
I get black fluid each year out of the wheel circuits but the control circuits I am leaving for every three now as they are seldom contaminated. I have seen some that were really bad so you have to do it once to see what effect your environment has on it and adjust intervals accordingly.
