Flaring brake lines is a process of enlarging the end of a brake line to create a flared fitting. This fitting allows the brake line to be connected to other brake components, such as calipers and wheel cylinders. Flaring brake lines is a critical skill for any mechanic, as it ensures that the brake system is properly sealed and functioning correctly.
There are several different types of brake line flaring tools available, each with its own advantages and disadvantages. The most common type of flaring tool is the single-flare tool, which creates a single flare on the end of the brake line. Double-flare tools create a double flare, which is stronger and more durable than a single flare. Hydraulic flaring tools are the most expensive type of flaring tool, but they produce the highest quality flares.
