My bike was driving me crazy today! One of the brakes pads in my disc brakes [on the front] kept sliding out. I would jam it back in there, but it wouldn't seat properly. The instructions say there should be an audible click when it is properly seated, but mine won't do that. It's too grunged up from all the winter salt, mud and crap I guess. And the brake cable for the back is semi-seized, it won't release the brake completely and I get an extended drag whenever I use them. And my chain is skipping a bit and the shifter cable is completely seized -> no gears. Major suckage, I guess I'll be working on my bike tonight. This is why I wanted to build a simple single-gear bike for winter. But I couldn't afford it. Dammit!
