Abstract
A plug for sealing an aperture in a brake actuator housing is provided that provides improvements in installation and retention of the plug and protection for sealing surfaces. The plug includes a retention member including a body defining an aperture configured for alignment with the actuator housing aperture along an axis extending through the apertures. The retention member further includes a plurality of alignment tabs extending radially from the body. The tabs are configured to be received within a plurality of notches formed in a retaining ring affixed to the housing when the retention member is disposed in an unlocked position and configured to be disposed on a first side of the retaining ring when the retention member is rotated about the axis to a locked position. The plug further includes a seal configured to be received within the aperture in the body. The seal closes the second aperture.
