ABSTRACT:
A device for mounting a cam shaft for actuating the brake shoes of a drum brake for vehicles and the like, in which the cam shaft is mounted in a bearing eye of the brake bracket via a bearing section by a bushing, includes a tigthening disk and a guard ring for restraining axial movement of the cam shaft. There is a bearing section in the brake bracket for rotatably supporting the cam shaft on a section adjacent to the S-shaped cam. And, to avoid too much grease on the brakes and to increase the low maintenance or allow for no maintenance of the device, the bearing eye has an extension on the other side of the cam away from the cam and beyond the bearing section to define a grease chamber enclosing the cam shaft.
