I was changing My rear brake pads on My 2004 GSA R 1150 and the anti rattle bracket fell out, when I tried to replace the original I broke one of the tabs off, the My parts man sent a replacement and one of those tabs broke off. I was told by the service manager that it is only held in by friction, there is no grove for the tab to click into.
