All the bikes i've been on and they've been running the Coust pads. Well, there brakes have been preety shit to be honist with you, they've had no noise and no bite and the lock wasn't to good either, I don't see what all the fuss is about them, there rubbish. All I can recomend is to sand the pads down a ml or so and your rim a nice fresh sharp grind, if that don't work i think it's time for some new pads.
