ABSTRACT:
A drum brake device is provided in which a stroke before effectuating the parking brake effect of the brake shoes is restricted so that any disconcerting feeling to the driver and any delay in effectuating the parking brake when in an emergency situation are eliminated. The drum brake device includes a pair of the brake shoes 20, 21, a pivot lever 36 pivotally provided at one of the two brake shoes 21, a shoe clearance adjustment device provided between one end of the pivot lever 36 and one end of the brake shoe 20, and a strut provided between the other end of the pivot lever 36 and one end of the brake lever 28, wherein the braking force is transferable between the two brake shoes 20, 21 through the connection with the pivot lever 36. This produces a duo-servo type of brake device. The brake shoe 21 functions as a trailing shoe in which the lining wears slower when the service brake is in operation.
