I was starting to go over the Coronet today in prep for the upcoming driving season...check fluids, brakes, grease front end, etc, etc. I need to ask a really stupid question...how much brake fluid do I put in the master cylinder? I've never had a car w/ a single reservoir and a screw on lid. Do I fill just below the threads? or all the way up? Thanks! Bill M 65 Coronet 500 'vert
