FIELD: car industry.
SUBSTANCE: invention relates to brake systems of vehicles. A friction node for a brake system contains an overlay of friction material, containing friction and fastening sides, a collecting groove, a sole, on which the overlay is located, containing a hole pneumatically communicating with the collecting groove, a vacuum source creating vacuum in the collecting groove and in the hole. The friction node contains a gas filtration device pneumatically communicating with the collecting groove and with the hole, trapping gases released by overlay friction and coming from the collecting groove, and a particle filter trap pneumatically communicating with the collecting groove and with the hole to filter the air coming from the collecting groove. The particle filter trap and the gas filtration device are made in the form of a thin layer of material, located on top of each other and on a support layer. The filtration device is located between the support layer and the filter trap.
EFFECT: pollution is reduced.
