What is the size of Volkswagen brake line fitting?

The size of a Volkswagen brake line fitting can vary depending on the specific model and year of the vehicle. Commonly, many VW models use a 10mm or 12mm fitting for brake lines, but it's essential to check the specific service manual or consult with a parts supplier for the exact dimensions for your vehicle. Additionally, the thread type (e.g., metric or standard) should also be considered for proper compatibility.
