IMPORTANT:
Please be advised that the tool used in this video is for SAE brake lines only. Most modern brake lines (including the Alfa Romeo GTV) are DIN so be sure to use the correct tool for your brakes lines!! These flaring tools are available for both SAE and DIN.
The exact brake pipe flaring tool used in this video is currently still available although I don’t know for how long. It can be found right here:
