Is it always super hard to get them on? The shoes on the cam side are against the rollers and the adjusting cone is all the way in. Are my cheap eBay brake shoes too big?
If the lining is riveted to the shoes , I file or grind a taper at the leading and trailing ends of the lining . I allow the taper to extend from the outer end of the lining almost to the first two rivets . Sometimes when the lining is riveted on it can cause s the lining to kick outward very slightly on the ends of the shoes , A taper on the ends will relieve the end drag and hopefully reduce the radius enough to allow the drums to go over the lining . The shoes need to be centered inside the drums , Usually by the time when the lining has to be replaced the tracks will be worn enough to cause problems with centering the shoes . Sometimes the brake cams can become stuck in the brake cam shaft . The cams must be free floating or the brakes probably cant center . Just a thought .
