Review on Cal-Van Tools 165 Master Brake Flaring Kit - Double and Single Flares, Professional Inline Flaring Tools. High-Quality Tool Set by Albert Tucker

I used this to double expand a stainless steel brake line on a car. It's far superior to the flaring tools you rent from auto parts stores. Works fine, but here are a few tips that will help: 1. Make sure your final preparation is perfect. The included cutter ensures a great square cut. Forget the included stainless steel deburring tool. It will not work. I used a dremel with a grinding wheel to remove the burrs on the inside and add a bevel on the outside. The bevel on the outside is crucial as it guides the fold during the process.2. When attaching the clip, gently tighten it so it rotates. Twist it around the tube until you feel resistance and squeeze. This is your peak that offers the best clamping force.3. Add an additional 0.05 inch to the end of the tube in addition to the flare length used for the measurement. That will help. provides more clamping pressure on the pipe and provides grip as you drive the anvil into the pipe.
