ABSTRACT:
A drum brake device is provided that functions as a very stable leading-trailing (LT) type when the service brake is applied, and as a highly effective duo-servo (DS) type with very little fluctuation in stroke when the parking brake is applied, in which strange noises are not generated, and any impact load is not applied to any of the components, thus enabling a lighter device. A shoe clearance adjustment device (12), adjacent to a service brake actuator (8) is suspended between the two brake shoes (2, 3). A parking brake actuator (18) is adjacent to an anchor (9). The middle segment of a long link (11) is pivotable in the middle of the one brake shoe (2). The ends of the link are functionally engaged with the shoe clearance adjustment device (12) and the parking brake actuator (18), respectively. The parking brake actuator (18) is equipped with a stroke adjustment device.
