yes, the rear brake is now my good friend that i was neglecting before. i'm guessing the same thing happend with my brake lever as your friends clutch lever the bottom nut fell off and then the squizing of the brake lever unscrewed the bolt. now i have to wait a seven to ten days before i can ride the Kat again. however this did enspire me to check all of the bolts on my bike to make sure nothing else was going to fall off.
