Don't know about a upgraded bracket but I have always just lubed the pins and it helps. When you take off the caliper pins just use some brake clean to clean the pins and the holes they go in. I used a little compressed air to dry them off. Make sure not to mess up the rubber o rings. I used the Ford OEM caliper pin lube. It comes in a tube and is available at the stealer. Just lube them up and reassemble. There are boots over the ends of the pins just be careful not to tear them.
