The invention relates to a system for capturing braking particles from a friction brake system, which has a vacuum source, a pneumatic circuit which connects the friction brake system to the vacuum source, and a filter located on the pneumatic circuit and mounted on a support. The capturing system comprises a control unit and a detection device for the filter which is capable of sending at least one signal to the control unit, the control unit being capable, on the basis of this signal, of identifying the absence of the filter and of informing a user of this absence of the filter.
