ABSTRACT:
An elongated strip having spaced-apart air scoops formed thereon is adapted for installation within the brake drum of a truck for creating a flow of air across the braking surfaces of the drum in response to rotation of the drum. The strip is installed against the interior surface of the drum exterior wall adjacent the outer periphery thereof and is secured in place by the drum mounting studs or other threaded fasteners inserted through strip mounting holes in radially inward extensions of the strip upon alignment of those holes with the drum mounting holes. A second embodiment employs a plurality of strip sectors of arcuate configuration connected in end-to-end manner with a back sheet cooperating to define an air compression/flow cavity between it and the interior of each air scoop.
