that problem start in my 03 accord. went to the dealer service, they said it was normal. here is the reason:
"the brake pads switch positions (depending on the rotation of the rotors) thats why they make that noise)
seems pretty stupid why honda would build something like that.
and another thing is that even w/ few weeks old brake pads, they squeak and their reason:
"they are semi-metalic and they will squeak. its normal"
i'm probably gonna get rid of this accord.
