This is a pretty simple do-it-yourself project to help tune up these calipers – cleaning the gunk out of them when they get dirty. I also discuss how to reset the dial so that it is pointing straight up – when these get dirty, sometimes the gear will jump a tooth on the rack and the dial will not zero out with it pointing up.
