I picked up my bike from the LBS, with a new derailleur, brake pads (I have front & rear disk brakes), new cables, etc. I was all ready to get a nice ride in before the sun wend down. I reached the bottom of the hill near my house, and my front brake totally fell apart.

Fortunately, my LBS was still open at 6 pm, and they told me to bring it right in. It turned out that the manufacturer had put the wrong brake pads in the package. The ones they put in there were very similar, but not quite the same. I was lucky. The back pads could have easily fallen out too, and I would have been totally brakeless going down a hill into a 4 lane busy intersection.

Everything's fixed now, so tomorrow I'm looking forward to a 40 or 50 miler.
