I just changed my pads, and damn, it was a easy job. If you have a few sockets, a jack, and an hour of time, you can save $200. Let me know if you want directions.
If you did need new pads, a chirper would sound. It makes an annoying ringing noise. you can also tell by looking at the break pad. Either take the wheel off and if you can see it through the rim, and see how think the pad is.
