Mark; No, I can't identify the brake cylinder. New one on me. However, I wanted to point out something that you've probably already checked. This will have little, if any, impact in the short term but may have in the long term. Depending on which brake fluid you're using, not all O-ring materials are compatible with all fluids. Automotive and aviation brake fluids are not the same, so check compatibility or you may have problems with deteriorating or ineffective O-ring seals.
By the way: somewhere in the recommended practice manuals it says if your airplane has sat on the same heading for a year or more or has had any significant metallic items changed in the cockpit, you'll need to re-swing the compass. Get busy! ;o) Oscar Zuniga Medford, OR
