The missing bolt

A partner in my firm offered to assist me in fixing mamba so I drove her to his place in Laguna beach. We took the wheel apart to inspect the calipers. While I was anticipating a complete brake system overhaul, within 5 mins it became obvious that one of the two bolts securing the calipers to the main body was missing.

This caused the calipers to have some play and binding the rotors when the wheels moved backwards. Easy to fix? Maybe...but it took us 2 hrs to find the right bolt. The Germans and their damn wierd metric bolts with abnormal threadings. Finally, I put some threadlock on the bolt and screwed it back and MAMBA is alive again!! I was so elated that I wanted to drive back home in reverse. I spent a couple of minutes talking / consoling her when I got back. Old age is catching up with her.
