Ironic that you said that. Took mine out for a shake down and everything felt fine. Came back started to clean up and couldn't find my 10mm snap on allen socket. At that moment I realized I'd fucked up. I took the socket off the ratchet and spun the bolt on the rear caliper by hand. Then got distracted, phone call i think. And didn't go back to tighten it. Socket still in the bolt. Once I realized this I checked the bolt only in half way at this point and socket is gone. Got my other socket and tightened it, thank God it didn't back all the way out on my shake down ride. Rear brakes would have failed and probably locked up and broke stuff. Once that was squared away I walked the driveway in hopes to find my $30 socket. And there it was by the mail box.
That whole thing could have been worse if I hadn't left the socket in the bolt and it not been missing when I cleaned up. Then on my gap trip next weekend the bolt backed out and put me in the hospital.
