Abstract
A resilient seal cap is coupled over an upper opening of a reservoir casing to define an interior air space with the upper surface of brake fluid in the casing. The seal cap is formed integral with a first annular lip co-operating with the inner wall of the casing to provide an inlet check valve permitting the flow of air into the interior air space and with a second annular lip co-operating with a valve plate secured to the center of the casing to provide an outlet check valve permitting the flow of air out from the interior air space to the exterior.
