Abstract
A friction assembly for a brake system able to collect vapors resulting from the friction of a lining. The friction assembly for a disc brake system includes: —a lining made of friction material, including a friction face, an attachment face opposite the friction face, and a collection groove that is open on the friction face; —a sole plate, supporting the lining, including a hole; —a negative pressure source configured to create negative pressure in the collection groove and the hole. The friction assembly includes a gas filtration device, in pneumatic communication with the collection groove and the hole, able to collect gases resulting from friction of the lining and coming from the collection groove.
