3/16" steel lines have a 3/8" flare nut, and the rubber flex lines will have 5/8" wrench sizes on both ends. The line coming from the master cylinder to the front and rear T-blocks will probably be 1/4" diameter tubing with a 7/16" nut. The upper end of a rubber flex line will also be locked into a bracket on the frame that restricts it from turning, but I always use a flare nut wrench as a backup anyway.
