Elément de progressivité (29) d'une friction d'embrayage (10), notamment pour véhicule automobile, constitué, au moins en partie, en une silicone d'addition. A friction device has a center axis (A) and a mid plane (P) perpendicular to the center axis (A). The friction device comprises first and second shields coaxial to the center axis (A) and pieced together to form a radially emerging peripheral slot between internal faces thereof, first and second friction linings fixed to external faces of the first and second shields, first connecting torques made in one piece with the first shield and having a circumferential orientation, second connecting torques made in one piece with the second shield and having a circumferential orientation, and a progressiveness element disposed in the peripheral slot and pressed between the internal faces of the first and second shields. The second connecting torques are inclined with respect to a plane of the second shield towards the mid plane (P) of the friction disc. The progressiveness element at least partly comprises an addition silicone.
