ABSTRACT:
A drum brake includes a brake shoe having a web, a hand brake lever pivotally attached to the brake shoe by a rivet extending through the hand brake lever and the web and having a stepped rivet shaft formed of adjoining first and second rivet shaft portions and a spring disc mounted on the rivet shaft to compensate for a play between the web and the hand brake lever. The spring disc is situated between the hand brake lever and the web and is firmly riveted to the web by the first rivet shaft portion passing through the hand brake lever. The spring disc has a central radial annular portion of an outer diameter which is greater than the diameter of the first rivet shaft portion. The spring disc further has at least one spring tab starting at the end of the outer diameter of the annular disc portion and extends out of the plane thereof.
