How to double flare a brake line

Published at : 13 Dec 2025

In this video I will be showing you everything you need to know to properly and safely create a double flare or SAE 45 degree flare on your brake line. I will show you all of my personal tricks and tips so that you can be successful and not get frustrated making failed flares. Lots of great info in here that the popular Youtubers don't teach and they don't teach in books! This is not a hard job but with my tips and tricks you'll become a brake flare master! This is important gearhead stuff to know!

This is another episode of a new series on how to become a GEARHEAD! If you have ever wondered how people know so much about cars and are absolutely crazy about anything with a motor, then this is a great series for you. This is geared towards people that have no knowledge of cars but want to learn; however, the content in my videos does try to make solid connections between theory and practical applications so even seasoned gearheads will find the info useful. Tired of paying other people money to fix your car? Then ya gotta learn this stuff!
