The best I’ve ever used. Working with plastic coated steel lines are never fun but this tool worked perfectly. The handle is removable for them really tight areas, grips so tight without marking the line all up, flares perfectly every time. I am comparing it to my 20 year old tool that kept slipping or the double flare looked more like a single, then I purchased a new kit from amazon similar tool as my old but also didn’t work, purchased this and done. Just a tip I used a blow torch and Brillo pad to remove the coating from the line in seconds 👍 I used to scrape and sand them down this way was a lot faster, not to mention cleaner.

This thing is Amazing. I dont see how anyone who can follow simple instructions cant flare a brake line. Believe me if you can't make this tool work you should not be working on something as important as brakes. It is so easy. Cut and deburr tubing slide on your fitting the thead side down. Then take the tool thread the given alinement stop bolt in the end and slide the tubing in firm against. Then tighten the 2 10m bolts to secure it to the line. Then take outo the alinement tool then take the die and thread it in the side marked operation 1 first and tighten until it bottoms out. Dont forget to greese it first. The unbolt the die and greese the other end snug it down. Then back it out and back off your 10 mm bolts and it's good to go with a perfect flare. I was doing a complete system so I was doing several flares. I used my 20 volt brushless 1/4 in dewalt impact driver to tighten the 10 mm bolts and to drive the 3/4 8n bolt. Not sure if that's recommended but it sure made things go fast. You just got to be smart and not get crazy and I had no problems. Out of a entire under the floor brake job I only had to redo 2 flares. Once because the tube slipped when tighten it down and wasn't in the tool enough. I mean it was a flare but not very pretty. Then the other was the typical thing we all do. I forgot to put my threaded fitting on. The line first and had to cut off a perfect flare. My only down side to the tool is the handle. I know they wanted it to be able to remove it so it could be used in a vice. The down side is it just screws in hand tight and it always backs off and the tool wants to spin in hand if its loose. Other than that this thing out the box will make flares like some of 400 dollar sets. For the price and quality job it does I am okay with it. Way better than the old kind that you clamp the tube between 2 bars and then slide the flaring tool on the arms. Then you had to use a little button thing and press again for a double and they never make the double ones well. They do Ok at a single flare but who is going to do brakes with a single flare? Also I would like to state that I ran a copper nickle line. I can not speak to how well it would do on steel lines. But I doubt it would have to much trouble. Also I seen someone say he had to modify the alignment bolt so it screwed in 1mm closer or something. I never had that issue. Maybe he had one that they missed on quality control who knows. But overall don't think twice if you need to do brake lines it's amazing. I got to run a 5/16 tube for fuel I was going to use the old style flare tool since it is very little pressure any way with a carb set up. But I might buy one like this in the bigger size. We will see. I hope this helps someone so they can decide to make a solid purchase of a great tool. You can look at my reviews I have done several and they are not all good and I am not paid. I call them like I see them I just think this is the most bang for the buck for this type of tool.

I tried a $30 tool and it did not work. The above flaring tool is the best tool that I have used for flaring brake lines. The "vice" for holding the tubing uses 10mm bolts to compress the fitting. There is no movement of the tubing when the bolts are tightened. Fittings to flare the tubing are strong, solid steel. My first try using this tool was successful. My subsequent flarings were successful with no leaks, More tubes will need to be flared to fix other tools flares. Need to have a tube cutter, a 10 mm wrench and a 17 mm wrench to use the tool. My kit did not have these items. This is the best flaring tool i have used.

I have had this tool for a while now and wanted to use it for a few different times to give and accurate assessment...well here's my story....For decades I have been using those cheap flare tools. The ones that come in the cheap plastic box (usually red in color) The ones where you clamp the tube in the hole between two die halves using the undersized wing nuts that you could never get tight enough to keep the tube from slipping. I've had to redo more flares with those cheap tools than i care to even remember. They rarely came out perfect, they were always slanted or not quite flared enough...but i do remember all of the skinned knuckles!! Just to get one good flare could take multiple tries and the better part of and hour. Well i had to redo the entire braking system on my old jeep. I was just dreading this job. So I got on everyones favorite video site and looked or a different way. There I found a video reviewing this Capri brake flare tool. I was impressed with the video so I ordered one. When it arrived i followed the instructions did a couple of practice flares. No kidding, they all turned out first try. I never knew it could be this easy. Once I got the hang of it i could do a flare in a minute or two rather than the normal 1/2 hour or so. I was able to unscrew the handle and place the body of the tool in my vise which made flaring even easier...it is near impossible to to use the cheap tool with a vise as the vise jaws are in the way and you also have to remove the tool from the vice and undo the wingnuts every time you started a new flare...With the Capri you can leave it in the vise until you are finished all of your flares!! ...and...you can use a wrench or a ratchet to create the flare rather than twisting with your bar hands on those other near useless cheap tools. also, this Capri tool appears to be made of hardened steel as my vise did not mar it up much even after being clamped tightly....Spend the extra money on this quality tool and forget the other ones even exist. You can thank me later...would recommend 5 stars.

I bough this to repair a brake pipe on my 41 year old VW. Both ends of the existing pipe had rounded off union nuts so i couldn't replace it without some serious hassle.I cute pipe in half and changed the cylinder at the same time, i bought a pack of unions and joiners and added a new union to the pipe still on the van and made another short pipe up and connected it all up. Works perfect and saved me a load of hassle. A bit expensive i guess but its superb, highly recommended. Far better than the type you need to clamp in a vice.

Rear brake lines were rusted and broken so I decided to buy the kit that came with a cheap flaring tool (garbage) and the line, connectors, etc.Being unable to create the tube ends using the cheap tool I started searching until I found this tool that saved my day. It worked very well making both types of flare. It is strong and handy allowing to get it into tight spots. Highly recommend!
