ABSTRACT:
A brake actuating mechanism comprises a housing formed of facing shells with an elastomeric diaphragm suspended between them. A centrally disposed opening in the housing permits an actuating rod disposed within the housing to reciprocate through the opening. The diaphragm also has a centrally disposed opening. A pressure plate having a tubular section engages one side of the diaphragm. A spring is disposed between the pressure plate and the housing. The actuating rod extends through the opening in the diaphragm and is press-fit into the tubular section thereby simultaneously compressing the edge of the opening against the tubular section to form an airtight seal.
