I decided to dig in and replace the parking brake shoes because I wasn't getting any holding effect when pushing the parking brake pedal down. In retrospect I probably could have just made an adjustment.
Adjusting the parking shoes is a PITA because you need to remove the calipers.
By pulling on the cables (one at a time) I was able to get them unhooked where the one to two bracket is. This gets the cable loose enough to get the lever out and then new one in. I got new boots but did not install them because it looked like too much to take apart. The shoes come off without pulling the axles. See videos (1AAuto?) on Youtube. I installed the new shoes, hold clips, adjusting screw/etc. that came with the complete kit. Don't break the 8mm bolts that hold the clips. I'd say unless there is a lot of rust/etc. you can use the old clips (add locktite) and adjustment "screws". Clean and re-grease. I used the new parts in the full kit I got.
With the adjustment all the way "down" I installed the rotors and was able to see that when the pedal is pushed all the way down I got some parking brake effect. I'll probably need to readjust soon or when it won't hold on a hill. As mentioned adjustments is a PITA, lots of seemingly needless wrenching. The caliper bolts should be installed with Loctite and re-installed with Loctite, so they take some torque to get them out. I think the install torque is 80 lbs-ft. Check that. I just put them in "tight".
The whole project was a good amount of work because I spent a considerable amount of time figuring out how to get the parking brake cables loose. I couldn't see how to loosen the cable near the pedal.
