I totally agree Koneisland,properly setup they are not heard outside of the hoistway by the general public. An elevator mechanic may hear a soft clunk only because they are looking for it. If you hear a loud Brake, it needs adjustment. The distance between the drum, and brake shoe is critical to cutting down the noise factor. As a FYI, it my understanding that Kone won't let their Tech's adjust the Brakes until they have been trained and certified. Anyone hear of this?
