Barely any Brakes

With the drum off, so you can "learn" what you are doing, you have to use a tool or extra screwdriver to lift the ratchet off the wheel. Usually, you can stick a small driver in there at the right place and push almost directly outward to release the ratchet. I actually haven't done this in several years, and different cars are a little different. A small flashlight helps.
