Hmmm, you have me thinking now. I had the problem appear after I replaced my front
control arms with the 03 Cobra arms. Of course, this involved a complete disassembly of the front
suspension. Now, there is a metal piece in the front caliper that's supposed to keep the front pads from moving in the caliper. The metal is thin and wears out after a while. I wonder if the brake pads are rattling in the caliper?
A bit of web research leads me to think that this is the problem. I recommend changing the anti-rattle clips on your front brakes. The parts numbers for these are... Front set: Raybestos H5658; Rear Set: Raybestos H5625A.
I'm going to see if the rattle goes away when I apply my brakes...I sincerely hope so. I want to fix this rattle!
