I looked at the springs and they seemed Ok but the small ones on the bottom didn't have any tension. I replaced the shoes and all the springs , so far so good.(one day) The drums are original and look OK.
Can someone explain how this could be happening. How can the brake shoe kink itself so tight ,it locks up the wheel??
Is it possible the rear end could be the culprit here also? There is alot of play there.

Thanks
