Terry, I put on Brand new Ford rotors (again) so there was no runout problem at first.
I wire brushed the hubs before installing the rotors to ensure there was no dirt.
Ford wants $90 for the bracket so I told them where to put it. I took the sheet metal approach for now to see if it would improve the condition while reserving the welding approach for the future if it doesn't work.
I did it on wednesday and so far the squeeking noise is gone. The pads move in the groove, but all the clearance is gone now. I am monitoring the temperature of the rotor with and infrared temp meter to see if there is a variation with the right and left side. So far so good. I am thinking about upgrading the brakes so I didn't want to drop a bunch of money on hardware just yet, only to have to replace it.
Terry, How freely should the pad slide when it is in the bracket? It slides now with gentle pressure, and it may loosen up more as time goes on. Perhaps I should file the shim down a bit more.
