how do i know what kind of brakes i have on the back of my car..drum or disc

look behind the rear wheel and see if it looks like the front wheel. If it is disc brakes, you will be able to see a silver looking disc. If it is drum it will look like a metal bowl nothing silver showing. Hope this helps you I don't know any other way to tell you, if you haven't been around cars much.
