I purchased this tool in order to replace the brake lines on my Jaguar XKE Independent rear suspension. When I first looked at the results that this flaring tool produced, I was very skeptical as the bubble flare did not look at all like the bubble flares that are professionally done.
Seeing that if any of these brake lines leaked, I would have to completely remove the complete IRS in order to repair the leak, I was hesitant, but I decided to simply follow the instructions (Very skimpy) and do the brake line installation.
To my surprise I installed all of the brake lines and not a leak to be seen. After almost a month of use there still are not any leaks from any of the eight brake line connections.
This bubble flaring produced some of the easiest tubing flares that I have ever done.
