Right on. Over years of normal braking, the shoes wear down the internal surface of the drum. However, it also results in a small ridge forming around the inside edge of the drum where the shoes do not make any contact.This ridge is preventing you from removing the drum.Brute force will probably work, as some of you have suggested. For me, it's always been easier to reverse rotate the adjuster (a wide bladed screwdriver will work), thus collapsing the shoes a little. The drum then just slid right off.You don't have to worry about the adjustment at this point either. You'll have to go through the adjustment process anyway after installing the new shoes.One other unsolicited suggestion: I've done a lot of drum brake jobs, so I strongly suggest you invest in the proper tool to remove and install the springs. The tool is not expensive, and those springs are strong. I've seen guys try to do them with long nose pliers and/or screwdrivers, and they've resulted in injuries. Just my $.02. Good luck.
