I was wondering what you all thought about changing the rear brakes. I know mine are low. The parking brake doesn't even stop one of the wheels from rolling. I'm on a very tight budget. My brother brought my car to his automotive class one day for a demonstration on how to change the rear drum. They said it was too rusted to get off. Should I attempt to do it myself? Or is it worth it to save the hastle and have a shop do it? Is it possible that since it's so rusted, that it will be damaged when taking it off and I'd have to buy new parts for it? If so, I'll do it myself, and just upgrade to rear disks....
