I've read about the rattle fix that was posted here about using .001-.002 shim stock wrapped around caliper pin. Which is a good temporary fix. The fix I use is replacing the #13 caliper pin with the #23 p/n on the front brake parts exploded view on any of the honda parts stores. The lower pin has a noise dampener part of the pin (rubber sleeve) which I use on the top part of the caliper as well as the bottom hole. Now there are two noise dampening pins which eliminate any rattles.I also make sure I grease the pins with white lithium grease,I have had great results. Give it a try.
