I've got a rattle in both front brake calipers that refuses to go away no matter what I do. When brake pressure is applied the rattle goes away, but any little crack or bump in the road causes an awful metal on metal rattle. And don't even get me started about dirt roads. I'd heard the pad clips are bad and that causes it, so I replaced the pads and put new clips in. The rattle went away for about 300 miles and now it's just as bad as it always has been. I think the problem is the fact that the caliper is two parts? I really don't know but I'm so fed up with it that it's ridiculous. Anyone have any ideas or do I need to try all new calipers?
