[QUOTE="davidd, post: 94573, member: 1177"] Rob, I think that determining the correct pivot points would be a difficult task. In fact, I think Trevor said as much earlier in the post. But, brakes with pivots always will display asymmetric wear. The leading shoe will also wear more compared to the trailing shoe, as has been discussed. I think the best way to solve the problem is to replace the pivots with floating ends. Floating shoes have a "virtual pivot" point and produce very even wear. I think this can be done by simply cutting off half of the pivot ring on the shoe. I have not figured out the shape of the pivot that remains, but I suspect it could be milled in a slight "Y" shape. You would need a second spring near the floating pivots as a return spring. This mod would also allow you to join the two pivot posts with a plate so that they support each other and do not bend towards each other as they do on the steel backing plates. I think floating shoes would be a pretty good substitute for pivoted shoes. David [/QUOTE]
