Electric Brake Performance Issues

Thanks to all who responded and I apologize for the confusion on the pads vs. shoes. All of my road vehichles have pads and that's what I normally work with and mis-stated pads for shoes. Very helpful information and the manufacturer recommendations were as stated in one of the posts as too adjust to a tight tension and then back off to a slight drag. I had a chance yesterday to free spin each wheel and the brake functions seem to work correctly. I also tested my voltage to the magnets from the controller as well as ohming the magnets and all checks passed and were in the correct ranges. The only thing I haven't had a chance to do is to drive the trailer and set the shoes. I will do that over the weekend and post my results. Again, very grateful for the responses and very helpful information. Still learning the electric brake systems. Thanks, Larry
