My front callipers rattle like crazy and its driving me nuts. I can't believe I'm the only one with this problem, yet I can't find any other post discussing it. Is there a spring or something to stop this? Is there a part number? Where do I go to get it? O'reilys couldn't find it. A picture would be great. I did find a spring/clip laying on one calipar and shoved it in where I thought it would go. It stopped the rattle but only lasted one day. Then I shoved a piece of rubber in there and that lasted about 3 days. The rattling is most noticeable at low speeds and particularly in parking garages.
