adjuster
My problem turned out to be a seized parking brake cable. Just a year ago I last replaced both rear cables.
When I discovered it was a seized cable, I managed to unseize the cable with a propane torch.. Two or three times during last Winter I lubricated the cables. I purchased a special grease that supposedly could not be washed away, it is messy and is like blacktop.
I realize it is useless just changing these cables and think that will solve the problem. Somehow they have to be lubricated.
What seized cables do is wear the shoes prematurely, cause the linings to crack, overheat the drums, when vehicle is moving there is a tick, tick sound. Overheats the wheel rim and can damage the tire. I had a slow leak in the wheel I was having the overheating problem every two days I would top up the air. When the weather got warmer it was every day. I took the tire in last week and was told the tire bead was damaged and could not be repaired. Had to buy two new rear tires.
I believe I have now finally discovered why every year I have to replave my rear brake shoes and have to deal with this brake drum overheating problem. PROBLEM IS A SEIZED PARKING BRAKE CABLE.
