This!, I have had a few CB hubs that had this issue now that I was reminded, one Suntour and one Sachs Jet CB hub. The brake shoes on both had really weird wear marks when I cleaned them up, I changed out the Suntour pads with good used ones but it made the hub much worse, cleaned everything up real good and looking at the shell, you could see that the shell wear marks were uneven like it was egg shaped, I cut the hub out and striped it for parts. The Sachs was the same way but it took longer to figure out cause I had no parts to swap, finally gave up on it and built up a Shimano CB hub and laced it in there. I checked the hub with a T inside mic and sure enough it was warped, not by much but enough that it was noisy and grabbed hard when braking.
