A movable brake dust recovery unit that may be disposed adjacent an automotive shaft after the wheel has been removed therefrom, and thereafter subject the backing plate and associated brake shoe assemblies to a current of air to remove particled foreign material therefrom.The current of air with entrained dust and particled foreign material is directed into a confined space where the air is washed and then subjected to the action of a filter. The washed and filtered air may then be safely discharged to the ambient atmosphere without danger of contaminating the same. During the above-described operation the brake shoe assemblies and the interior of the brake drum are subjected to a rotating blast of air to separate dust and foreign material therefrom, with the separated dust and foreign material being subsequently entrained with a current of air and carried into the confined space.
