The drum brake (30) includes a pair of arcuate drum brake shoes (32, 34) supported relative to the backing plate (18), with the shoes (32, 34) having a pair of opposed brake shoe ends (36, 38) engaged by the actuator (40). The actuator (40) comprises a pair of levers (42, 46) pivotably attached to one another with each lever (42, 46) having a second lever end (48, 58) engaging a respective end (38, 36) of an associated brake shoe, wherein the second lever end (48, 58) has either a slot (49) or an edge (59) located laterally away from the other and engaging the associated brake shoe end (38, 36).
