That was my problem. The cable had just a slight amount of tension, and apparently that was just enough to push on the shoes and cause them to grab. I loosened that nut at the equalizer bar to the point where it sags down, and it made a huge difference. I thought as long as the shoes were resting against the pin on the backing plate it was all good. But today, I learned that wasn’t the case. The drums read 74 degrees and 87 degrees. You can actually touch them without burning your hand.
