Ok so I went to re grease my bearings, and noticed that the breaks pads, I think, are slightly rubbing on the drum. I was thinking as it sat for maybe 5 or so years something froze up. Would it be advisable to just take everything out and re set it? The ellectric emergency break was tested and it reset after I put the pin back in it. Also, I haven't worked on drum breaks in like 30 years, lol. And ideas where to start would be apreatiated.
