ABSTRACT:
A drum brake device that functions as a leading-trailing (LT) type when the service brake is applied, and as a duo-servo (DS) type when the parking brake is applied, in which the automatic shoe clearance adjustment mechanism functions precisely for a prolonged period, thereby generating no strange noise. This mechanism also eliminate any impact load applied to any of the components, thus enabling a lighter device. The middle segment of a long link 11 is pivotable in the middle of the one brake shoe 2.
