Great and reliable setup to have in the toolbox
I've had the pleasure of using copper brake lines on multiple vehicles, and I have to say, they’ve consistently exceeded my expectations. Whether it’s for my own car or helping out friends and family, these brake lines have proven to be a lifesaver on more than one occasion. First off, the product is incredibly easy to work with. The copper material is pliable enough to be bent and shaped without much effort, making installation a breeze. What’s even better is that the fittings all threaded perfectly with no issues at all. Whether I was working with a custom setup or standard connectors, everything lined up smoothly, and I never had to worry about leaks or cross-threading. I've had to rely on these brake lines several times when others have run into brake line issues, and it's always been a relief to open my toolbox and have the exact length I need on hand. The copper is not only durable but also resistant to corrosion, which gives me peace of mind knowing they’ll hold up over time. All in all, I highly recommend these copper brake lines for anyone looking for a reliable, easy-to-install solution for brake line repairs or upgrades. It’s saved me a lot of time, hassle, and stress, and I’m sure it will do the same for others!

so far, so good, now to see if it lasts longer than the unibody!
just installed right rear side today. 4 car jacks, 14 inches off the pavement. nickle is ferromagnetic. check it out online for yourself. whether this is electroplated, i can't say. but it bends super easy, compared to regular FAKE rustproof steel lines. cut off end looks like pure copper alloy. no visible coating. no tubing bender was needed; just my fingers. after flaring, it looks like copper inside and outside. the 2 types of flares [double and inverted] needed; only took one attempt. looked perfect; not lopsided, or thin. this is my forth shadetree mechanic brake line job in 40 years, previously using local crap auto store aftermarket rust proof! 3/16 brake lines. their rustproof exhaust pipes & mufflers have the same claim to fame! 18 months! previously, i used unions & preflared various length lines to get from A to Z the last time. NO FLARING tool last time. not all that easy either [PIA!]. this time i used zip ties to lay it out along side the old HEAVILY RUSTED rust proof[ we promise!] lines[ 4 yrs old!]. the exact time it took to do the right rear to the master cylinder is up for grabs. 4 hours total. includes trip to zettlers for misc frame clamp screws , blaring sun/ light rain breaks & i also checked other things while it was off the ground[ 95 cougar]. starter, pulled 3 tires, check exhaust leak from egr tube[went nowhere!], then readjusted a wheel cylinder after replacing one drum shoe adjuster that also rusted out in 4 yrs. the rest of rear brakes were done, while waiting for last adjuster to come in. they kept sending the wrong side! thanks for nothing auto parts store! read the other nickle/copper line reviews for all amazon sellers here. spend the extra money, if your life, other drivers and time spent is worth it! MGD/modelo time can wait! measure thrice, cut once! this is a winner, i hope. no LEAKS at either end,OF COURSE! time will tell, on this old car. be sure and use new frame clamps, [leave the stiff plastic old ones alone!]; to stop vibration noise and later line fatigue. undercoat or silicone seal around the drilled holes first, if you're paranoid. OHIO winter SALT! the included fittings are not my cars thread type. loose or too large.[metric or sae?]. I just reused the 2 old fittings. if you need new ones, buy the shortest line at store, cut it & you have 2 fittings for less then the price of buying 2 fittings. store managers hate that! the old trash 16 ft of tubing cracked open, under the stress of folding it up for the trash , right at the heaviest rust spots [not at clamp points either!]. didn't miss the binding arbitration lawsuit with the auto junk store!! DO NOT do this for someone else's car as the really nice guy you are!, if you dont want to go lawsuit broke and feel as if you're being divorced later for 30 years! sell the complete system renewal job [including booster, shoes, drums,discs & ALL cylinders or FORGET IT! now it's beer break time! now for the left rear side next week [thursday]. measure thrice, cut once. take time outs. it helps. my left knee is inflamed 5 hrs later now. WHY!? use kneepads! i usually do. was this insightful for the shadetree guys!

Quality brake line
I had to run new brake lines on my 2006 Subaru Legacy. This line has been very easy to work with, very flexible and easy to flare. It looks like a high quality material that is not going to rust quickly. I've only ride about 30 miles after the installation, hence hard to comment on long-term performance at the moment, will update the review in a bit.

In general very good product
Overall this product was very good. It is a softer type brake line and bending this to shape was incredibly easy without a tool! They also flare nicely and easily because of the type of material. It was delivered extremely quickly so I can get my repair done. My only complaint with the product, which is why I rated 4 stare is the fittings it comes with. They work and do their job, but if you need to remove them for any reason after installation without a flare wrench they are not as solid and sturdy as the OEM fittings and will round off on you, I learned that the hard way. Overall an excellent price and product. They won't rust like the steel line counterpart and are very easy to work with.

Great replacement lines for daily driver
Really easy tubing to bend by hand without kinking. Robust enough to handle a double flare. Obviously softer than steel line, but holds up well with compression fittings or flare nuts. You get a lot of it for the money, and the supplied nuts are excellent. Size is true compared to the OEM GM lines. No leaks or deformities so long as the tooling and technique you use is good. I would recommend.

Great value and so easy to work with.
Used this to replace lines on a Nissan Frontier. I was able to replace my entire clutch hydraulic line and multiple brake lines with plenty left to spare. This stuff was a joy to work with and I would recommend it to anyone. I have a pair of tubing bending pliers from Hobo Freight that really helped with tight bends but otherwise you can bend it by hand super easily with no kinks. Just take it slow. Couldn’t find a better value than this.

Easy to work with!
I've used alot of steel brake line over the years and most required a tubing bender, not this line! It bends easily with just your hands and double flaring is really easy. I replaced about 20 feet of steel brake line on a boat trailer and had zero issues. Included line nuts were also a plus as I needed them to complete the project. Next time I need brake line, I will definitely purchase again when I need steel brake line.

These brake lines are fantastic. Replaced all the lines in my vehicle without having to have pre-bent lines with many unions. Just one solid line.

So easy to install! Bends and flares are so easy to make! Just flare one end and shove er in- hook up the front end and run it back, bending and attaching mounts as you go- Line it up with your rear connection, cut, flare, install- done! Actually made brake line replacement fun! I tried using oem quality steel tubing which must be pre bent before install and gave up after making the first flare- this old car wasn’t worth that level of effort. I’m very happy with this product!

High quality copper nickel tube. You will likely need 2 coils (50 feet) for a small car if you replace all the lines. You will also need a tubing straightener and a high quality flaring tool.
