Last Saturday, I spent hours beating on one of my rear brake drums trying to get it off. I used about a half a can of WD40 and even used a bolt to pound on the back of the drum doing no good. I tried prying and pounding for a long time, but it would not budge. I happened to read a tip online by a guy saying he had one stuck and he poured some soapy water on it and in 5 minutes with hardly doing anything, it popped off. I thought I don't know about that. Later I went back out to pound on it again and on the way out asked my wife if she could bring me a cup of soapy water which she did. I poured it on and within 10 minutes it came off! Who would have thought? Today, I had the brakes off and couldn't get one of the adjusters to turn. I sprayed some WD40 and couldn't get it. My wife said, maybe you should try soapy water. So I poured some on and guess what? It broke free first try! Don't know if they were both flukes, but I'm not going to complain!
