This "fade" might just be due to the fact your linings dont fit well.. I struggled with a similar problem for ages. Be careful not to just get linings put them in and hope they work, my 56 had new linings when I got it [imported] but they weren't thick enough. You guys in the U.S. often talk about "arching" the linings ,well here in Australia we just buy over size linings to match the diameter of the drum, standard , 1st, 2nd and 3rd oversize. you match them they work, I could not believe the difference when I finally worked out what was wrong. I have the power booster and dual circuit setup on mine and boy brakes are dynamite !
