what are you cleaning the brake with? i rode a megamo with a rear 185mm avid disc and the brake was IMMENSE! forward and backwards. i think you should go for a brand new set of pads and a rotor, being careful not to touch the braking surface as this can feck up a brake big style. set it up well and just give it a few wet rides and dry rides to let itself bed in, without giving up hope of it ever bedding in, it will sweet looking bike by the way, muchos gealous
