K-H brake swap done, but doesnt stop!

well, got them rebuilt, but never again! I will use them for the time being but will be looking for some 1973-76 A-body calipers, rotors and spindle/hub so next time these calipers need rebuilding, i will swap it all out for the single piston style. I fought with thise damn dust boots till i was blue in the face, trying to get them to stay put while installing the pistons..what a pain in the rear! FINALLY got them done.
