I had the brake recall done. It is a piece of foam installed in the fluid area and a 150g weight in the cover area to change the frequecy of the vibration. I think it is a track issue. I have never heard of street riders having brake failure due to trapped air from foam. But, BMW must have had some reason to do this. Some people are using the little shock mounted brake fluid cup off the small GS bikes. It will bolt onto a K1300 no problem.
I left the foam piece in the cup and removed the weight. In general, I have found when you have a vibration issue on a bike and take action that is not well thought out, it just shows up somewhere else. (I was worried the whole darn fluid cup would break off with that weight in it since it is only held onto the master cylinder with a couple of small screws and an oring and it is plastic.) There is also a National Traffic Safety recall, #09V38400, for all K1300's switch gear. This just came out two weeks ago and we will probably see a letter from BMW when it all comes together. beech
