Abstract: A disc brake assembly includes an anchor having a pair of spaced apart inwardly facing contoured surfaces between which a disc brake backing plate having an outwardly facing pair of complementarily contoured surfaces is located. There is a pair of slipper springs, each of which may be interposed between an outwardly facing and corresponding inwardly facing surface in either one of two distinct symmetrical positions. The two slipper springs are substantially identical and include a U-shaped portion with a leg extending from one U end so that the leg may form an abutment contact between a backing plate surface and the anchor surface during brake application. The two distinct symmetrical positions comprise one position with the leg extending generally inwardly from the U-shaped portion toward the brake disc axis, and another position with the leg extending generally outwardly from the U-shaped portion away from the brake disc axis.

Abstract: A linkage for connecting a brake cable to an actuator lever in a drum-in-hat park brake assembly. The linkage is defined by a continuous wire that is shaped into a base with parallel and adjacent first and second legs located in a first plane perpendicular to the base and parallel and adjacent third and fourth legs located in a second plane perpendicular to the base. The first and second legs each have a first section that extend a first distance from the base to a first loop and a second section that extend a second distance from the first loop to a second loop while the third and fourth legs extend a third distance from the base. The base has an opening defined by a complementary shape created between the first leg and the third leg and the second leg and the fourth leg.

Abstract: An actuator mechanism in a drum-in-hat park brake having a housing with a first end that engages a first web of a first brake shoe and a second end that engages a second web of a second brake shoe. A lever pivotally retained in the housing has a first end that engages the first web and a second end with a hook thereon for receiving a loop end of a linkage connected to an input member. On receipt of an input force the lever pivots and exert an actuation force on the first and second webs to correspondingly moves first and second friction members associated with the first and second brake shoes into engagement with a drum to effect a brake application.

Abstract: A drum-in-hat park brake assembly having a first brake shoe retained on a backing plate by a first pin and a second brake shoe retained by a second pin. The first and second pins permit the first and second brake shoes to be moved in a radial plane and to rotate about an axis of an opening in the backing plate. The first and second brake shoes each have a first engagement end which is aligned on the backing plate by an anchor post and a second engagement end which is selectively spaced apart by an adjuster mechanism. A spring arrangement urges the first and second brake shoes toward the anchor post and into engagement with the adjuster mechanism. An actuator assembly is connected to the first engagement end of the first and second brake shoes and upon receiving an input force moves first and second friction pads associated with the first and second brake shoes into radial engagement with a drum.

Abstract: 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.
