Abstract:
In a parking brake having a first brake shoe with a first end engaging an anchor post on a backing plate and a second end engaging an adjuster and a second brake shoe with a first end engaging said anchor post and a second end engaging said adjuster, an actuator being located adjacent said anchor post and engaging a first web on said first brake shoe and a second web on said second brake shoe, and a brake cable connected to said actuator assembly for providing a force for moving said first and second brake shoes into engagement with a drum to effect a brake application, said actuator being characterized by a housing having first and second side walls that extend from a base, said first and second side walls each having a first end with first and second ears thereon which are joined together along a central plane extending through said base to define a first slot there between, said first slot being substantially perpendicular to said first and second side walls for receiving a first web on said first brake shoe, said first and second side walls each having a second end with first and second ears thereon with the first ears joined together along said central plane and with said second ear on said first side wall being located in a same plane as said second ear on said first side wall with said second ear on said second side wall being substantially parallel with said second side wall, said first and second ears on said second end of said first and second walls define a second slot there between, said second slot being substantially perpendicular to said first and second side walls for receiving a second web on said second brake shoe, a lever having a shoulder located between a first end and a second end, a pin for pivotally locating said first end of said lever between said second ears on said second end of said first and second side walls such that said shoulder engages said second web on said second brake shoe, said lever having a hook thereon for receiving said cable to locate a button on said cable adjacent said second end of said lever, and resilient means located between said second ear on said second end of said second wall and said lever for maintaining said lever in said central plane such that an input force applied by movement of said second end of said lever by said cable is communicated through said shoulder into said second web to move said first and second brake shoes into engagement with said drum to effect a brake application.
