1. Friction assembly for a brake system, comprising:
a lining made of friction material, comprising 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, comprising a hole in pneumatic communication with the collection groove,
a negative pressure source configured to create negative pressure in the collection groove and the hole,
wherein the friction assembly comprises a gas filtration device, in pneumatic communication with the collection groove and the hole, the gas filtration device being capable of capturing gases resulting from the friction of the lining and coming from the collection groove, the friction assembly further comprising means for condensing gases resulting from friction of the lining.
