Finally trying to convert my car from drum to discs in the front and ordered the right stuff kit for 14 inch rims. Well I got the drum brakes off, but for the life of me I can't figure out how to get the backing plate off. The instructions say to just remove the anchor pin, but it doesn't have a nut head or anything on it. I can't figure out if it's just pressed on or what. I've given it some good smacks with a hammer and nothing. Am I missing something obvious? Any help would be great. Thanks.
