I was wondering if anyone out there has done a brake/hub swap on a 10 bolt front from 1/2 ton to 3/4 ton? I have heard that it is fairly common, but figured someone in this group would know. I have been told that all I need to do is change the rotor, the hub (to 8 lug) and the backing plate. The calipers are the same? I am running a 14 bolt ff in the rear, do I need to change the proportioning valve? The master cylinder will be upgraded to the 3/4 ton version.
