Actually no. I didn't find it and that was a problem. Yesterday I started hearing an abnormal noise coming from the front end. I also felt something through the bars. It didn't feel or sound good and started getting worse. I poked around and couldn't see anything blatant like a piece of plastic flapping around. Then I hit the front brakes while riding home from work, normal stop, nothing crazy and I heard this God awful screech and felt the vibration in my hand. "OK, I think I have a brake problem."
I took yet another look, pushing/pulling & kicking. I couldn't find the clanker. I suspected the right side as the cause for some dumb reason. I had my hands all over the right side caliper and didn't notice anything as a result of that cursory examination. I decided to replace the pads and managed to find a set. I did the right side first. Everything looked fine and normal wear on the old pads. That kinda pissed me off since I was convinced that it was the right side.
I moved over to the left and started loosening the 2 bolts that hold the caliper. When I put the hex key on the top bolt I immediately could tell it was very loose. I shook the caliper and could see it move too. I unscrewed it the rest of the way out by hand and there weren't many threads.
Here's the part that sent a chill through me. The bottom bolt was gone.
You can provide yourself with the probable outcome if I had continued to ride without catching this. I am the only person that wrenches on this bike so I can't pass the buck to a mechanic. I forgot to tighten them last Sunday. Do me yourself a favor, find the time to check your fasteners for tightness more often. Yep, I'm kinda freaked out.
