  • Brake drum cleaner
    Patent number: 4670062
    Abstract: An apparatus for cleaning brake drums includes an inflatable toroidal seal for establishing a dust-tight seal between the brake assembly and the apparatus, an air jet for causing asbestos particles to become airborne, an exhaust fan or turbine driven by an air motor for vacuuming the airborne asbestos particles into a filter bag, an internal atomizer for producing a mist of liquid within the apparatus to settle any residual asbestors particles, and a set of pushbuttons arranged in the order in which they would normally be used for controlling the various modes of operation of the apparatus. The apparatus may also be used for cleaning clutches.
