well i'm giving the dealership a call on monday. i even called autozone today but they couldn't even order them. they said they usually sell them for $8-$12. so hopefully the dealership won't kill me.
and WCS, i'm not sure what caused this to happen. no one has touched my rear brakes ever up until now, and i can't think of what underlying problem could cause it.
and hondatech, stop posting here.
