I went up to the shop yesterday to put the front brakes together with the new rotors and rebuilt calipers. The reason for reworking the brakes was that I had noticed last year that the outer pads on both sides were not making full contact with the rotors. When I got the right side back together and gave the rotor a spin, there was a slight rubbing sound and I found that the caliper is not centered on the rotor, but offset outward by ⅛", explaining the aforementioned wear anomaly. I will remedy this by installing 1/16" hardened steel washers as shims between the caliper ears and the spindle mount. BTW, the old rotors were nearly ⅛" thinner than the new ones. Thoughts on shimming the calipers?

While I was there, I collected the rear shoes to send them out to Porterfield to have them relined with their "street" compound to match the new front pads. When the rear axle was disassembled to install the Quaife ATB diff, we discovered that the grease seals on both sides were leaking and that the rear brakes weren't doing much of anything. The inner surfaces of the drums are smooth and I will clean them up today and do a proper inspection, but I'm wondering if anyone knows what the limit on I.D. is should they need to be turned. I did a quick check and they appear to be uniform with an I.D. of 9". Does this sound right? I will have the relined shoes arced to match the drums.
