1. A brake dust particle filter for a disc brake assembly comprising a brake disc and a brake caliper, wherein the brake dust particle filter is configured to catch particles generated during braking; the brake dust particle filter comprising:
a housing shaped as a ring segment and comprising two axially spaced apart housing side walls and a housing peripheral wall extending radially outwardly in relation to a central axis of the ring segment in a peripheral direction of the housing,
wherein the housing peripheral wall is arranged between the housing side walls,
wherein the housing is configured to accommodate at least partially the brake disc in a housing interior of the housing;
a tongue projecting inwardly away from the housing peripheral wall into the housing interior,
wherein the tongue projects at least in sections with at least one radial component,
wherein the tongue has a flat cross section shape comprising:
at least one base surface facing the housing peripheral wall,
an end face projecting into the housing interior, and
at least one side face;
a filter medium,
wherein the tongue is formed by the filter medium;
wherein the tongue comprises
no supporting device components separate from the filter medium, and
the filter medium that forms the tongue is configured to maintain the flat cross section shape of the tongue during filter medium removal from or insertion into the housing;
a filter element, wherein the filter element includes the filter medium;
wherein the filter element further comprises a curved outer contour corresponding with an inner contour of the housing peripheral wall of the housing.
