Today one of my rear drums seized up; the shoes tightened up some how? Backed off the shoes and pulled the drum, cleaned components etc... I then noticed that my ebrake was not backing off, i pull the handle up and when i release it the cable does'nt move. I did a search of the threads and am wondering if it is seized bellcranks or a seized cable. I pulled the cable at the rear of the truck and the mechanisms seem to move on the out side of the drum. Any thoughts input in helping me diagnose the problem?
