1. A system for suctioning braking particles from a friction braking system, the suction system comprising:
at least one negative-pressure source (1), at least one suction mouth (83), at least one pneumatic circuit (3,3′,30) connecting the suction mouth and the at least one negative-pressure source, and a control unit (6),
wherein the suction system further comprises closure means arranged on the pneumatic circuit, the closure means being able to isolate at least a first portion of the pneumatic circuit (3), the control unit (6) being configured to control the closure means according to a predetermined logic in order to isolate the first portion of the pneumatic circuit during certain phases between two actual uses of the at least one negative-pressure source, the predetermined logic being such that inside the at least one pneumatic circuit a negative pressure is maintained during deactivation of the at least one negative-pressure source (1).
