I am looking to replace all of my brake lines. Mechanic suggested to replace as they are rusted and there is air in the system. I matched it up and they seem to be 3/16” what size do you guys use and how much is necessary I got 25 feet of 3/16” in copper. Also what is recommended brake fluid? I know it’s DOT 4 but is there any specific brand for MB or European vehicles?
