I took another look at it. Turns out when I dressed down the flanges for the caliper mounts, I left them less than perfect. I cut a few thousandths more off and the caliper now slides nicely, and disc ALMOST does not bind. Tomorrow in the daylight I'll take one last swipe or two with the bastard file and it should be right. Then, I'll have to grind down the corners of the calipers to clear the wheels. I already talked to the tech at ABS and they say it's ok by them ( I won't be voiding my warranty ). I made a template from poster board to guide my efforts with the grinder.
