Types of Brake Line Flaring Tools

Traditional

The traditional brake line flaring tools use a bar and yoke to flare lines. The use of the bar is to clamp the brake line in place while the yoke drives the flare adapter into the line to create a flare.

Hydraulic

The Hydraulic brake line flaring tool is the most convenient of the three. It uses hydraulic power to drive the flare adapter towards the line. It makes your work much easier and less effort on your part.

However, hydraulic brake line flaring tools are expensive. It’s definitely worth it though since we are talking about the brakes in your car. It’s always better to invest more when it comes to your own safety.

Compact

Traditional and hydraulic brake line flaring tools are often too large to use for flaring lines on cars. Compact brake line flaring tools are known for their single opening for lines and interchangeable adapters. They will fit any tight spaces under your car.

However, they are only compatible with one diameter of tubings. Their extreme usefulness in tight areas still outweighs this.
