What Are Brake Lines Made Of?

Automotive brake lines on classic cars are often made from seamless steel tubing specifically designed for hard-hitting applications and engineered to resist the acidic properties of brake fluid. traditionally these lines use a 45-degree duplicate flare connection, but many builders prefer the search of AN brake lines and their 37-degree single flare connections. additionally, flexible bracken lines can be made of stainless sword, Kevlar, or even rubber .

Hard Brake Lines 

There are several reasons why a hard-line bracken occupation assembly is preferred over its flexible counterparts. For one, a solid brake lineage is much less susceptible to swelling, bulging, and even electric potential cracks. Being that the brake system on your car is hydraulic and exerts extreme pressure ( phonograph record brakes can see over 1,500 psi ! ), you want the brake lines to be a durable as potential .
Most vehicles have 3/16 brake lines, either in regular 45-degree flare fittings, or AN brake lines with 37-degree solar flare. These flares can not be desegregate. These brake lines will work equitable fine in most applications. even if you are doing a dispatch, frame-off restitution or plumbing a vehicle from boodle, there is no reason to increase the diameter. You may see 1/4 brake lines in older four-wheel brake drum brake applications, but with advanced braking promote 3/16 brake lines will work good ticket .
Hard bracken lines are normally made from bare steel, plastic-coated steel, or corrosion-resistant stainless steel steel, but a nickel copper brake line adaptation is besides available. Each character of sword has its own properties, cost associated, and ease of bend and flare out characteristics, therefore choose what your budget can afford and what your bending/flaring tools are capable of. Brake lines stainless steel or other hard materials will require a quality flaring tool to create leak-free lines.

Flexible Brake Lines

Where possible, Speedway recommends using upstanding brake lines. Cars are made to flex, and the connection between the brake caliper and frame/body should be made with a compromising bracken hose, such as AN 3 brake lines .
compromising brake hoses are not what they once were and are a lot less prone to bulge and swelling. High-quality, elastic bracken lines are made from durable nylon material. It is then lined with a stainless-steel enmesh to help fight the extreme imperativeness exerted on the lines .
AN 3 brake lines are the most used elastic lines for performance applications, but we have several brake agate line adapters and fittings to fit about every application to allow you to adapt flexible AN 3 brake lines to your 3/16 bracken lines already on the vehicle. From domestic to import, imperial to metric unit, we got you covered !

How long Should Brake Lines Last?

Hard sword brake lines can well last decades, however, you will sometimes find with vehicles that sit a batch or have excessive moisture in the brake system will see rust, leaking lines within a few short years. This number can be affected by a variety of factors including, upwind conditions, usage, and the amount of tenor put on the system .
Of course, rubber brake hoses are much more prone to cracking and road conditions. Servicing the brake arrangement, such as replacing the disk brake pads or adjusting your drums on your vehicle gives you the perfect opportunity to inspect the overall condition of the brake lines and hoses. This periodic determine should include everything from the master cylinder to disc/drum circumstance.

If potential, compromising brake lines should be changed every 6 years or at the beginning sign of the zodiac of wear. We like to suggest if you are replacing a disk brake caliper then replace the flexible brake hose attached to it a good. Brake line steel tube should be replaced every 10 years or sol depending on the discipline. If you live in the “ rust belt ” states and drive your cable car year-round, these numbers could be significantly decreased. Corrosion, particularly on older vehicles, is the number one factory of brake line failure. obviously in warm, dry climates and where brake systems are regularly flushed and replaced with new fluid, steel brake lines have been known to end much longer. If your plan is new to you and you do not know for certain the condition of the hard and flexible brake lines it is best to replace it all, so you have “ Day 1 ” date as to when the brake lines were put into service .

What Happens When A Brake Line Breaks?

The brake system on your vehicle is under ceaseless coerce during application of the brake system. When a bracken pipeline gives way, all or most of the fluid will escape. In plow, this means that your ability to stop may be decreased or eliminated depending upon how your brake system is plumbed and type of chief cylinder in use .
Movies and television receiver shows serve as the arrant model for providing a ocular illustration of what can happen. You press the bracken pedal point but nothing ; the car does not stop, which can lead to vehicle damage and personal injury. Rust or corrosion is a great indicator that it may be time to change out your brake lines .
If you have had a bracken channel that has burst while you are driving, you know the feel of panic that immediately sets in. In the unfortunate event that this happens, pump the brakes, and pull over ampere soon as possible. While much mistakenly called an emergency brake or “ E-brake ” your fomite ’ sulfur parking brake may be used in these situations to aid in bringing the car to a barricade. Once stopped, do not attempt to drive it far. It is good to have it towed to your shop class or garage for repair of the brake system. The little tow poster is better than trying to nurse it home and potentially having an accident !
If you want to avoid this trouble all in all, grab a accomplished brake line kit from Speedway Motors nowadays ! Universal kits will come with the necessity flare nuts and a seethe of your intend tube diameter. They are available in length ranging from 8 feet and go all the manner up to 40 feet, which is adequate to completely plumb all four wheels and the master cylinder on just about any car or truck. Vehicle-specific kits will include all the necessary hardware such as hangers and clips with pre-bent tube that are cook to install on your vehicle in minutes.

How Do I Know If My Brake Lines Are Bad? 

several indicators may tell you it ‘s time to change your brake lines. Some are more obvious, while other issues can be more obscure. Our best advice is that if you have to think about changing your brake lines, just do it. Don ’ deoxythymidine monophosphate put it off until it ‘s besides former .

Leaking Fluid 

The most common gestural of bad or raddled brake lines are leaks. The bracken system is designed to be a seal unit. much like the coolant and oil in your car, leaks are never a good signboard. If you have determined that there is a leak from brake lines, change them immediately. The most coarse leak points are the solar flare fittings/seats where sword or AN brake lines connect to junctions, rack cylinders, and the dominate cylinder. however, lines can rust from the inside out or be damaged by abrasion from moving driveline parts or road debris .


We mentioned this earlier, but external corrosion caused by road salt or sea salt in the air travel, and general moisture in the fluid itself, can wreak havoc on your car ’ s brake lines. Older vehicles such as muscle cars will have steel brake lines that were probable not made from stainless sword or other corrosion-resistant materials. time and the environment will take a bell on a cable car ’ sulfur bottom, causing potential brake problems if rust eats through the lines .
