Soft pedal after hard turns

IMO, first reset the endplay to near zero or even a tiny bit of preload, secure the locking system, then roadtest it.
>If/when the problem returns, check the endplay. If it has changed, then unless the bearings are soft a butter, most likely the cups are still not seated
I use the old cups to press in the new. If you don't have a press, I have a machined block that I drop in there and pound the back to back cups in. On my bench, When the cups bottom, the hammer bounce-back changes, and then I know it's in.
Don't forget the other side.
>If the endplay DOESN'T change, and the pedal-problem remains; then IDK what is going on. But remember to put the backlash back.

EDIT
I checked and the endplay is actually ZERO to .003.
The procedure is to tighten to 90 inchpounds while rotating the disc; then back off by one slot, and slip the cotter pin in..
