Abstract
A fluid-operated brake actuator having a housing with one or more vent openings in communication with an interior chamber is provided with a filter assembly mounted to the housing over the vent openings. The filter assembly includes a gas permeable filter element, with oleophobic and homophobic characteristics so that air entering the service brake inner chamber from the atmosphere will be substantially free of contaminants
