Internal parts of cars can seem super complex to owners of a vehicle. However, when you break it down into small parts it is much easier to piece it back together. When getting into brake lines the same things apply. One of the most important parts of a brake line is the flare. Flares need to be performed properly to keep a tight seal. If you notice leaking from your brake lines it is most likely from the quality or type of flare.

So do brake lines need to be double flared? Double flares are necessary for brake lines due to the high pressures inflicted on them by the hydraulic system. Single flared lines are only appropriate for low-pressure lines due to their tendency to crack or leak. The brake system cannot afford to have a leak in the lines since this can cause serious injury or death if the brakes fail. What is the difference between single flared lines and double flared lines in a vehicle, and how do they affect your brake system? While some single flared lines may show up on cars that have been incorrectly repaired by a shade tree mechanic, a double flared line is the OEM standard for automotive braking systems and, as such, is a much safer option in the brake system to avoid any kinds of leaks or other pressure-related issues. The bottom line is that whether your car has SAE brake line fittings or DIN brake line fittings, it should never have single flared brake lines. The reason that single flared fittings are such a big no-no when putting your brake system back together is that a single flared fitting almost always tears the metal during the fitting and creates a chink in the brake line. Even if the flare does manage to hold a seal, there is still the chance of a blowout at that point in the brake line from that point on.
