Method and device for capturing particles ejected by the friction braking elements of a disk brake system

Method for capturing particles ejected by the friction braking elements (2) of a braking system (1, 2) with brake discs (1) of a vehicle, comprising:

• equipping said braking system (1, 2) with a capture conduit (3):
• provided with an upstream air inlet face (3a) and a downstream air outlet face (3b) and having a form adapted to accommodate the friction braking elements (2), and to conduct, when the vehicle is moving, an air flow for cooling said friction braking elements between the upstream face (3a) and the downstream face (3b),
• integrating a shutter (6) with a plate (6a) positioned between the upstream face (3a) and the friction braking elements (2),
• integrating means (5) for capturing particles ejected by the friction braking elements (2),
• controlling the shutter (6) so as to move the plate (6a) between a position for closing the conduit (3), set for vehicle travel speeds lower than a predefined threshold speed Vs, and at least one position for at least partially opening the conduit (3), for vehicle travel speeds higher than the threshold speed Vs.
