Abstract
The invention is drum brake assembly having a dual brake actuator. A piston-cylinder assembly forms the primary brake actuator, and a lever member, together with the piston-cylinder assembly, forms a composite structure which acts as a secondary brake actuator. The lever member pivots about an axis substantially parallel to the axis of rotation of the drum, and the lever member is contained within the drum brake assembly. The piston-cylinder assembly is operable independent of the composite structure to actuate the brake.
