Inside the hub is a conical Archimedean screw type device that expands a pair of steel shoes, that form a cylinder, when the pedalling backwards motion is encountered. The whole mess is collapsed by a circular spring around the shoes. So, either the spring or the shoes could be gnarled. The system is quite elegant but simple. There are books available on the subject and this could be your last hope.
