Woah, I never meant to start any arguments...I'm relatively new to cycling, and actually googled to see what the "cap" is actually called. Google bicycle brake cable ends and you will find links to the actual part. All I really wanted was an answer to a really simple question from people who have a lot more experience (or at least more than 2 months) than I do. Thank you to all of you who gave me an answer and simply understood what I was talking about. It is supposed to rain tomorrow anyway, so I'll just get it fixed up right after work on Monday and be done with it and not really lose any riding time.
