1. A system for capturing braking particles from a friction brake system, the capturing system comprising:
a vacuum source;
a pneumatic circuit which connects said friction brake system to said vacuum source;
a filter disposed on said pneumatic circuit and mounted on a support;
a controller; and
a detection device configured to detect said filter, the detection device being configured to send at least one signal to said controller, said detection device comprising exactly one pressure sensor which is located on said pneumatic circuit upstream of said filter, said pressure sensor being configured to send a measurement of a pressure (P1) in said pneumatic circuit upstream of said filter in the at least one signal to said controller,
wherein said controller is configured, upon receiving the at least one signal, to compare said measured pressure (P1) with a reference pressure (PR) which is the pressure in said pneumatic circuit in an absence of a filter for a reference operating state of said vacuum source during said measurement of pressure (P1) by said pressure sensor, said controller being configured to inform a user of the absence of said filter on said pneumatic circuit when said measured pressure (P1) is substantially equal to said reference pressure (PR) or is substantially equal to the atmospheric pressure.
