I just bled my brakes and now I can't get the reach adjustment back where I need it. I let the brake reach all the way out to bleed and now this adjustment is frozen. I put a socket over the adjuster and it turns (very difficult to turn by hand), but it is clicking and not registering anything. The adjustment doesn't move. Works fine on the front brake after the bleed. Any ideas? Couldn't find anything online. Thanks.
