Abstract
A dust guard is provided for a brake actuating mechanism comprising a housing having first and second end walls, an elastomeric diaphragm suspended within the housing, a brake actuating rod disposed within the housing for reciprocating movement relative to the housing and having a first end and a second end, the second end being directed towards the second end wall of the housing, and a spring disposed within the second chamber between the second end wall and the diaphragm. The dust guard comprises a resilient tubular barrier, attached at one to the second end wall, and extending inwardly axially to engage the actuating rod, or structure connected to the actuating rod, to isolate the second end of the actuating rod from the interior of the housing.
