Edit: I think I figured this out. I need to fully loosen the cable under the console, adjust the shoes, then retighten the cable.

I recently rebuilt my parking brakes on both sides, adjusted the shoes per the directions, and tightened up the cable under the console. After, the brake wouldn't hold on my inclined driveway.
I had been worried about not backing off the star wheel enough and having the shoes rub, so I expanded them a bit more. No luck. Went back under the console and tightened the cable to the limit. It holds now, but only if I really jack the pedal almost to the floor. This can't be the ideal adjustment. Wondering if I need to expand the shoes some more b/c the cable isn't an option any more. Any advice or suggestions are welcome.
I plan to do a mini-writeup soon sharing a few of the tips I picked up here and there. Least I can do since they saved my sanity. Somebody here said this job was their least favorite they had ever done on the 4R. Hallelujah, brother. Some of the thoughts I had about anybody who ever had anything to do with that design would probably get me locked up if I said them aloud.
