Recently, I had the front brakes replaced (w/new rotors) in my 2000 Grand Caravan. Ever since then, whenever I brake at low speeds (it may also occur at higher speeds and I just don't recognize it) I hear a crinkling sound that sounds like it is coming from all throughout the frame. It literally sounds like someone is crumpling up cellophane or aluminum foil or doing something with corn starch. I'm not sure what this is. Any thoughts?

Are the brakes still under warranty from the shop that did the work? And does it sound like the sound is coming from the front or the rear? I would have the shop look at the brakes and let you know what is going on.
