I have a 1973 850 Commando that was stored with the brake resevoir empty. What Dot number brake fluid should I use? An old service manual lists Lockheed 329 hydraulic fluid but I don't have a clue as to what that is equivalent to. Sorry if this is repeat basic information, but I couldn't find it in a search for "brake fluid" on old posts.
