I was replacing the driver's front wheel cylinder and noticed a bit of grease on the inside of the drum. I also noticed that the bottom brake shoe is not worn at all... but the top one is. I then noticed that the fairly new rubber grease seal that goes on the inside of the drum (inner bearing seal) had little bits of shreadded rubber around it (like you get from a pencil eraser) and the metal band was showing... I believe that whatever it is supposed to seal up against might have a scratch or a nick in it... but I am not totally certain what it is supposed to ride against.
It is a '65 link pin front end. Of course... one of the two sides' king-pin component's are also bent slightly and I have it shimmed WAY out, but that shouldn't cause this problem.
