I had 3 people come over and look at it. All of them says the shoes and springs were correct. We are thinking that the self adjusters for some reason are adjusting itself every time I apply the brakes. I took out the self adjusters and it is not seizing the brakes anymore. The only problem I have now is the right rear drum gets hotter than the left rear. I pulled out the right rear axle and found out that there was hardly any more grease on the bearing. We are thinking that the first time it seized the right rear it burned up all the grease. Like I said, it was very hot and smoking really bad.
