<p>A drum brake assembly including two shoes arranged in end to end relationship and a torque spider having a plurality of diametrically extending guide pads or ledges spaced apart circumferentially and axially of the spider so that the axially spaced pads are in facing relationship to slidably receive a shoe web between the faces of the ledges for radial movement of the shoes into frictional engagement with a rotating drum. Two leaf springs are prestressed respectively between each shoe web and the face of one of the associated ledges to urge the web against the face of another of the axially disposed ledges to thereby maintain the shoes centrally positioned with respect to the drum and out of contact with the drum during brake release and additionally to suppress brake noise.</p> |
