Alright, fairly simple fix here. In the back of the brake shoes are pins that look basically like nails. The nails come in from the back, then a spring slides over the "sharp" end, and over that a washer like thing with a slot in it slides over, and twists to hold the springs in place. What happened here is that the washers popped off, and the nails were able to slide out, which caused the shoes to fold in half because of spring tension (kinda like folding a piece of bread in half). That being said, the issue is all taken care of now.
