A parking brake having first and second brake shoes with a first end engaging an anchor post on a backing plate and a second end engaging an adjuster. An actuator located adjacent the anchor post has a first end that engages a first web on the first brake shoe and a second end the engages second web on the second brake shoe. A brake cable is connected to the actuator assembly for providing a force for moving the first and second brake shoes into engagement with the drum to effect a brake application. The actuator is characterized by a housing having first and second spaced apart walls with a first end and a second end. The first and second ends each have first and second ears with the first and second ears on the first end being joined together adjacent a central plane mid-way between the first and second side walls to establish a first slot that receives the first web. The first ears on said second end of the first and second walls are joined together adjacent the central plane while the second ear on the first side wall is located adjacent the central plane and the second ear of the second side wall is located in a plane parallel with the second side wall. The first and second ears on the second end establishing a second slot that receives the second web. A lever having a first end with a shoulder thereon and a second end with a hook thereon is pivotally located adjacent by a pin extending from the second ear on the first wall to the second ear on the second wall and bring the shoulder into engagement the second web. A spring located on the pin between the second end on the second side wall urging said first end of the lever into the central plane. A button located on the cable engages the second end of the lever such that the cable is located in the hook. An input force is applied to the second end of the lever by pulling on the cable to cause the shoulder to exert a force on the second web while a corresponding force is exerted on the first web through the first slot to move the first and second shoes into engagement with the drum to effect a brake application.
