FIELD: brake systems.
SUBSTANCE: invention relates to a brake system containing a brake shoe (10), including a base plate (1) having a first side (13) and a second side (14), and a lining (2) made of friction material fixed on the first side (13), while the lining (2) is limited by the friction side (26), the fastening side (20), the inner edge (23), the outer edge (24), the rear edge (21) and the front edge (22), and the lining (2) has at least one collecting groove (3) open to the friction side (26) and exiting with its first end (31) from the side of the inner edge (23) and exiting with its second end (32) from the side of the outer edge (24). The brake system additionally has a suction system, which comprises a suction tube (40) through which air can be sucked in, and an injection tube (50) through which air can be blown, while the air inlet (41) of the suction tube (40) is located opposite the end of at least one groove (3) selected among the first end (31) and the second end (32), and the air outlet (51) of the injection tube (50) is opposite the other end of the said at least one groove (3) selected among the first end (31) and the second end (32).
EFFECT: capturing particles and dust from the brake system before they are released into the environment.
