Hey all, see attached picture. I am having issues with my '07 990 adventure rear brake not maintain pressure reliably. Even pumping does not help. I found that this nut is slipping since the shop last touched my bike when I didn't have time to work on it . On the parts diagram, it shows part 0934060003 HEXAGONAL NUT DIN0934-M 6 and it looks like there are qty: 2 so they lock against each other. Then I looked at other 990 rear brake push rod linkage pictures on images.google.com and most only have 1 nut. What's the right way and how should I resolve my issue?
