Frequently Asked Questions

What is the difference between a single, double, and bubble flare?

A Single Flare is a simple 45-degree cone, often used for low-pressure applications. A Double Flare (45°) is created by folding the tubing back on itself, providing a stronger, thicker seal required for high-pressure brake lines (common in the US/Japan). A Bubble Flare (DIN/ISO) creates a rounded, mushroom-shaped end, typically used in European vehicles.

Can I use a standard flaring tool on stainless steel brake lines?

Flaring stainless steel requires significantly more force than copper or standard steel. While some heavy-duty manual tools might handle it, a dedicated hydraulic flaring tool is highly recommended for stainless steel to ensure a clean, crack-free, and consistent flare without excessive physical strain.

What size brake line is most common?

The most common brake line size found on passenger vehicles is 3/16 inch (4.75mm). Many flaring kits prioritize this size, but a comprehensive kit will include dies for 1/4 inch, 5/16 inch, and 3/8 inch lines as well.
