Abstract: A disc brake assembly including a brake disc, a brake caliper assembly with a brake caliper, and a brake dust particle filter with a filter housing and a filter medium arranged in sections in the filter housing, wherein the filter medium extends beyond the filter housing in the circumferential direction of the brake disc and abuts against the brake caliper assembly. A brake dust particle filter for such a disc brake assembly is included, including a filter housing and a filter medium arranged in sections in the filter housing, which extends beyond the filter housing in the circumferential direction.

Abstract: A brake dust particle filter for a disc brake assembly is provided with a housing that has a first housing side wall, a second housing side wall, and a housing circumferential wall, wherein the housing circumferential wall extends between the first housing side wall and the second housing side wall. A filter insert with a filter medium is arranged in the housing and extends along one of the first and second housing side walls and along the housing circumferential wall. The filter insert has a curved circumferential edge. The housing has a curved receiving groove. The curved circumferential edge engages the curved receiving groove. The filter insert is L-shaped and is configured to at least partially cover a friction surface and a circumferential surface of a brake disc of the disc brake assembly. The curved circumferential edge of the filter insert projects past the filter medium.
