As seems to be the case for many other 8th Gen Accord owners, the brakes on my '09 EX 4 cylinder began squealing - in my case, once my car got to about 500 miles old. I tried de-glazing the factory rotors and pads, which only quieted them down for ~ 100 miles, and also deglazing the factory rotors and installing new Raybestos ceramic pads. Same deal, 100 miles later the squeal was back. Finally, at 17k miles on the car, I tried installing new Centric Premium rotors along with new Hawk Ceramic pads. I used the original factory shims (after careful cleaning with brake cleaner) with the new Hawk pads, putting the Hawk supplied lube between the backs of the pads and the shim surface, as well as between the backs of the shims and the pistons / tangs on the calipers. The sliders were cleaned, and I made sure the slide pins were lubed (but not too much grease, so they don't "hydraulically bind up"), and carefully reassembled the whole deal. So far (knock on wood so I don't jinx myself!), they are still quiet after 1k of use. The Hawk pads "feel" like the stockers, but they do dust a bit more aggressively than the stock pads - particularly in the front. While it's too early to tell if this is a permanent fix for the squealing brakes, it is effective so far.
