So I just got my first bike (or at least first bike since I was kid), and it's in pretty rough shape. It was free. It's an Azuki from what I believe to be the 70's. Both tires are flat, the front brake is broken, and the back tire rubs against the frame. This weekend me and a friend (who has had some experience in repairing bikes) are going to try to rebuild it.

I know pretty nothing about bicycles, but want to learn. I am a college student and a bicycle would be really great for getting around campus.

Do any of you have any tips for me?
