A brake cable for a dual mode type drum brake functioning as a leading-trailing type during the service brake and as a duo-servo type during the parking brake, may be easily arranged at a lower side of axle. The first and second brake levers (118), (119) of a parking brake actuator (117) have proximal portions (118a), (119a) pivotally supported between two ends of a second brake shoe (3) and at a lower end thereof; free ends (118b), (119b) extend in opposed direction from the proximal portions (118a), (119a) in parallel to face and functionally engage each other; a strut (120) extends between the second brake lever (119) and the pivot lever (16); and a brake cable (23) pulled to activate the free end (118b) is arranged adjacent to the anchor (7).
