Abstract

A brake dust particle filter for a disc brake assembly is provided to catch particles generated during braking. The brake dust particle filter has a ring segment-shaped housing with two axially spaced apart housing side walls and a radially outwardly positioned housing peripheral wall. The housing peripheral wall is arranged between the housing side walls. The housing accommodates the brake disc in the housing interior. A tongue projects inwardly away from the housing peripheral wall in the housing interior. The tongue projects at least in sections with a radial component and has a flat cross section with a base surface facing the housing peripheral wall, an end face projecting into the housing interior, and a side face. The tongue is formed by a filter medium and has no supporting device components separate from the filter medium. The filter medium provides a satisfactory stiffness keeping the tongue structurally stiff.
