    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.

    Good product at a good price

    My mechanic gets this all of the time. He even uses this on his own vehicles. It's of good quality and goes together easily. It's well worth the money.

    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!
