Do you have the original steel brake drums or cast iron brake drums? My brakes would fade when I was just driving around town until I switched out to cast drums. The problem is that the outer part of the drum expands so the lining only touches the inner part of the drum. (the side where the hub attaches). This becomes more pronounced after the drum has been turned a few times (which Ford recommended not to do).
Cast drums made all the difference in the world.
I got my drums and shoes from Randy Gross in California but he is a little far away for you.
