A system to reduce or eliminate brake actuator contamination by providing a clean air source for the actuator such that a volume of a void in the actuator can vary without introducing moisture and/or contaminants into the actuator. A movable wall moves in response to changes in the volume of the void of the actuator to compensate for the changes without drawing moisture or contaminants into the actuator housing. By reducing or eliminating actuator contamination the service life of the actuator can be extended. |
