Adhesive attachment of the disc brake push rod plate to the diaphragm

A spring brake actuator (100) having a push rod plate (134) and a diaphragm (130) is provided. A rim (152) projects from the diaphragm (130) for engaging a housing (118) containing the push rod plate (134). A sidewall (230) is connected to the rim (152), which is connected to a bottom surface (310), forming an outer diameter of the diaphragm (130). Flanges (190), perpendicular to the diaphragm (130), extend from the diaphragm (130) forming an inner diameter (250) for which the push rod plate (134) is inserted into. An adhesive (210) is placed between the diaphragm (130) and the push rod plate (134), wherein the adhesive (210) maintains an attachment and a seal between the diaphragm (130) and the push rod plate (134) keeping the diaphragm (130) and the push rod plate (134) in line with each other.
