Dual mode drum brake device |
摘要 |
It is an object of this invention to provide a drum brake device which solves a problem of decreasing the strength of a back plate near an anchor block and reduces potential damage to the parking brake cable. A pivot lever 60 is pivotally mounted on one brake shoe 20. Upper and lower portions of the pivot lever functionally engage with the other brake shoe 30 via struts 81, 70. A parking brake actuator 90 which pivotally supports on the upper strut 81 and activates upon an activation of a parking brake is arranged to be adjacent to a service brake actuator which activates upon an activation of a service brake. Preferably an operational part of the parking brake actuator is projected out from the brake back plate.
