13 . The dust sheet according to claim 1 , wherein a thickness of the dust sheet is at least 1 mm and/or at most 4 mm or at most 3 mm or at most 2 mm.

14 . The dust sheet according to claim 1 , wherein the dust sheet comprises a first layer, comprising the plurality of holes and/or the plurality of embossings, and at least one additional layer which is arranged plane-parallel to the first layer.

15 . The dust sheet according to claim 14 , wherein at least one additional layer comprises at least one cover layer, preferably a temperature-resistant cover layer, in particular made from a material that is flexible and/or soft and/or designed as a textile-like fabric or web.

16 . The dust sheet according to claim 14 , wherein the at least one cover layer is arranged on a side that is configured to face a brake disk and/or on a side that is configured to face away from the brake disk.

17 . The dust sheet according to claim 14 , wherein the at least one additional layer comprises an equivalent layer to the first layer, the equivalent layer being made of the same material as the first layer and/or having the same thickness as the first layer.

18 . The dust sheet according to claim 17 , wherein the equivalent layer is arranged at a distance of at least 0.2 mm and/or at most 0.5 mm from the first layer.

19 . The dust sheet according to claim 17 , wherein the equivalent layer comprises sub-centimetre damping structures for attenuating airborne sound, the damping structures of the equivalent layer being formed by a further plurality of holes and/or a further plurality of embossings.

20 . The dust sheet according to claim 1 , wherein the damping structures are arranged at least in a section of the dust sheet that is configured to face a portion of the brake disk that is opposite to a point of engagement of the brake disk with a brake pad of the brake system.

21 . The dust sheet according to claim 1 , wherein the damping structures are provided in a section of the dust sheet that is configured to extend over at least 10% of an area of the brake disk or at least 20% or at least 30%.
