The brake drum is full of dust, too. In the basin, aqueous solution washes away dust and keeps it from going airborne. This popular Ammco 1450 brake washer has an air-motor pump, hoses, a wand, and a brush. A filter sock in the drain and a dense filtration system trap asbestos and other contaminants. Consider brake dust containment and disposal before working on your brake system. Do not use a conventional shop vacuum on brake dust. Asbestos will pass right through the filter and discharge into the air. When replacing brake shoes, request non-asbestos lining if available.
