Thank you all for your informations,
I will send that to the management of the building, can be usefull for them. For my part I gave my notice and will vacate my appartement because like you can imagine it's not very easy to live near a Kone Ecodisc with drum brake not well adjusted.
I didn't know if that the people who worked on the brake was certified but anyway they are not very efficient because the noise is still here and it increase. And the only things they said is that "it's fixed" but in fact they didn't change nothing or they said "that is the normal noise of the brake".
