The invention relates to a brake dust collector (10) for a disc brake (12) comprising a brake disc (18) and a brake caliper (16) clasping the latter. The brake dust collector (10) includes a housing (24) designed to clasp a portion of the brake disc (18) directly adjoining the brake caliper (16) in the main direction of rotation (R) of the brake disc (18). Provided arranged in the housing (24) is a brake dust retainer comprising a plurality of brake dust intake ports. To ensure practically total retainment of the resulting brake dust without detrimenting, indeed, even improving the cooling of the disc brake (12) the housing (24) features a plurality of air intake ports (34; 38) separate from the inner brake dust intake ports, making it possible to direct the inflow of air in the direction of the brake disc (18) and into the inner brake dust intake ports.
