This tool came in very handy in replacing all of the brake lines (and proportioning valve lines) on a 69 Lincoln Mark III. The one small issue I had with it was that the die lock did not center perfectly by itself, so my first flares were lopsided. The die lock was catching on one of the studs and did not move all the way to center over the line. I had to tap the side of the die lock each time to fully move it over, and then the flares came out perfect. PVF coated steel lines aren't the easiest to flare, but the tool held the lines very well without slipping and flared without having to put in too much effort. I highly recommend this flare tool, just do a couple of practice flares first before doing your actual lines on the car!
Just did 4 flares for full brake line replacements under the car. This tool works great for close quarters, where you can't really wrestle with three piece flare kits. Easy to hold with just one hand and turn with a wrench. I've got both flare kits but this will likely be the one I use going forward.
No other tools needed. Cut line to required length and flare
I was a little skeptical of this tool but the reviews convinced me to give it a try. I'm building a VW tube frame buggy and installed disc brakes all the way around and needed to run all new hard and soft lines and I chose the copper/nickel tubing. Being a conglomeration of parts I need both bubble and double flares and let me tell you, this tool is foolproof, easy to use and gives absolutely perfect flares every time. I'm like you, as far as I know there's only one style of flaring tool out there. It's been the standard for over 50 years and I still have one but this tool is by far superior. I absolutely recommend that you get this tool. It's fast, easy and the results are perfect every time. Do it!!
