War wagon, I was thinking that as i made sure the drum turned freely, and now it is tight, so that might be what is happening, so I am trying to figure out how to hold the self adjuster tight so it will not turn/tighten.
The spring should have enough tension to hold the adjuster wheel in place. It may be time for new springs.
Also check that the E-Brake cable is actually retracting as it should. My 62 Dodge had this problem. Anytime I set the brake, the wheel would lock.
