Brake lines are a crucial component of your vehicle’s brake system. They are what allow the brake fluid to flow into the brakes, indicating how much pressure you’ve applied to the brake pedal. The best brake line material resists punctures, corrosion, and wear, limiting the chance of leaks that could prevent your brakes from working properly.
You can repair brake line problems by knowing how to fix rusted brake lines. Having said that, in many cases, replacing them is the best option. DIY installation of brake lines is relatively easy, though you will need some specialized equipment, including brake line flaring tools, brake bleeder, and brake line bending tools.
We’ve rounded up 9 of the best brake lines and reviewed them below. Check them out before you start your next brake line repair project so you can make sure you get the best brake line material for your vehicle.
Our Top 3 Brake Line Materials
Should I replace all brake lines?
If you’re changing the material being used in the brake lines, replacing all of them is a good idea. This maintains consistent pressure throughout your fuel system, reducing the risk of problems down the line.
Replacing all brake lines also makes it easier to keep track of your vehicle’s maintenance. It’ll be easier to remember when it’s time to change your brake lines if they’ve all been on the vehicle the same length of time and are made out of the same material.
Should you need to replace a brake line because of damage or wear, you may or may not want to replace all of them. Inspect the other brake lines for similar damage, especially if it’s a problem with rust. The age of the brake lines is a factor, as well. If they’re relatively new, the other lines may not need to be replaced.
Best Brake Lines: Full Product Reviews
The copper-nickel blend offers extraordinary resistance to corrosion from road salt. On top, it excels without a proactive coating. That’s why copper-nickel works best as brake line material. Nickel-brake tubes are popular in firefighting, military, and heavy-duty vehicles because reliability is paramount in these applications. The products reviewed here are not exceptions to popular beliefs about material and service, but each has its own exquisite upside worth an attentive read.
01. 25ft of 3/16” Copper Nickel Brake Line with Fittings
If you’re replacing the brake lines on an entire vehicle, a coil of wire is an affordable option. With this 25-foot coil, you’ll get enough tubing for an entire passenger vehicle. The kit also includes all the flare nuts you need for all-in-one convenience.
The copper-nickel alloy used in this wire is the best brake line material if you’re looking for both longevity and ease of installation. It won’t rust or corrode as easily as steel and is easier to bend and flare, too.
The only disadvantage of the copper-nickel alloy is that it’s not as resistant to punctures as steel. This won’t be a problem if you drive mostly in the city, but it’s not ideal for off-road vehicles. Barring punctures, though, this long-lasting brake line is durable enough. You may never need to replace it again.
Highlighted Benefits
- Resists rust and corrosion
- Contains enough lines and fittings for an entire car
- Includes 19 high-quality fittings
- The tube is easy to bend and flare
- DOT approved for use in road vehicles
02. 25ft of 3/16” Copper-Nickel Coil Brake Line, Inverted Flare
If you’re looking for the most affordable way to install hard brake lines on your car, check out this roll of copper-nickel alloy coil from Hikotor. You can get the fittings and line you need for an entire car for less than twenty bucks.
This copper-nickel brake tube is also very easy to install. It’s easy to bend, even compared to other copper wires. You can bend it by hand if you want, which saves you the expense of buying a specialized tool. Flaring the ends is equally simple.
You’ll love this brake line if you live in areas that use a lot of road salt in the winter. The anti-corrosion treatment prevents most wear, and since it’s a copper-nickel alloy, it won’t rust. Having said that, the same thing that makes it easy to bend makes it more likely to take puncture damage. It’s definitely a better option for city-dwellers than off-roaders.
Highlighted Benefits
- The most affordable way to replace all brake lines in a vehicle
- It can be hand-bent for easy installation
- Easy to flare even for DIY-ers
- Protected against rust and corrosion
- Comes with 16 fittings included
03. 25ft Roll/Coil of 3/16” Copper Nickel Brake Line Tubing
Let’s look at one last option for copper-nickel tubing. This 25-foot roll of tubing is sufficient for outfitting a whole car, similar to the two products above. The main difference is that it doesn’t come with any fittings. That saves you some money if you already have what you need, but it does add a step compared to getting a complete kit.
The brake line is very similar to the first product from The Stop Shop. The line is copper-nickel alloy throughout, with a consistent diameter for even pressure. Home mechanics will love how easily they can bend and flare this tubing.
We’d recommend this tubing primarily for use on cars that drive mainly in city and suburban environments. On rougher roads, the copper’s softness can be a disadvantage. In the right conditions, though, this tubing will last as long as the car it’s installed on.
Highlighted Benefits
- Easy to bend and flare for installation
- Contains enough tubing for an entire car
- Solid copper build allows for hand-bending
- It won’t rust, even in extreme conditions
- Consistent tube wall width for even pressure distribution
