Disc brake freezing at end of ride At the end of my last ride the back brake started rubbing hard on the disc. It almost feels like the brake cable had popped out of the lever. The bike is relatively new to me, and I am not very familiar with disc brakes. I can take it to the shop, but I wanted to be able to fix myself in case it happens again. Any ideas on how to fix, or what caused this? It is a Specialized Epic with Avid brakes.
Ensure the axle is properly placed in the dropout and the quick release is firmly closed. If it's even a little loose, the axle can shift a bit and cause the rotor to be misaligned with the caliper.
