Actually BigJohn, I've decided my bearings are still good. My pads are about worn out at 90 hrs because the calipers have been dragging. I'm using the pads in my unfinished kit to replace them and I have ordered new ones to replace those. The previous owner did not use the soft aluminum tubing for the brake lines as per the Construction manual. He used what appears to be a plastic tube with woven steel braid. It may be a superior line, but he did not put the loop in it around the LG leg and I think it is putting a side force or torque on the caliper that may be keeping it from backing off the disk.

Perhaps the braided lines are these...

I have installed RV-12 BRAIDED GEAR LEG HOSE KIT on my 12 that I operate mainly off grass runway. The soft aluminum loop was vulnerable to tall weeds, twigs, and foreign debris. The braided line is shielded by the gear leg. Good trade...

On a "brake lining wear"-related note, be sure that there is no physical interference between the aft end of the inboard wheel pant attachment bracket and the aft-inboard corner of the brake caliper. If there is such interference, the brake caliper/linings may not wear evenly.
