First, let me start off with the history of the rear caliper. I added a shorty cable, eliminating the parking break. I also put new pads on. It worked great for hours of riding and felt perfect. Then, while riding it just stopped working. I now have the caliper open and cant understand what is going on. The white plastic cap adjuster thing looks like it is adjusted all the way out and does not click anymore. Does anyone have any experience on what is going on? Is the mechanism broke or something? I dont see anything that looks broken.
