What to Look For in the Best AGS Brake Lines for Performance and Longevity
When I’m shopping for new brake lines, especially a set designed for better performance and a longer service life, I focus on a few key things. It’s not just about grabbing the first set I see; it’s about making sure they’re the right fit for my vehicle and my driving style. Getting this wrong can mean a lot of wasted money and, more importantly, a compromise in safety.
The first thing I always check is the construction material. The best AGS brake lines for performance and longevity are almost always made from Teflon (PTFE) on the inside, surrounded by a braided stainless steel sheath. The Teflon line is what the brake fluid actually flows through, and it’s fantastic at resisting expansion under the high pressure of hard braking. That expansion in standard rubber lines is what causes a soft, mushy pedal feel. The braided steel outer layer is there for serious durability, protecting the inner line from abrasion, road debris, and heat. This combo is what gives you that immediate, firm pedal response and the confidence that the lines won’t degrade over time like rubber can.
Next up is the fitting quality. This is a huge part of ensuring longevity. I look for lines that have high-quality, corrosion-resistant fittings, usually made from materials like zinc-plated steel or even better, anodized aluminum. Cheap, soft fittings can strip easily during installation or corrode into a mess after a few winters driving on salted roads. A clean, precise fit is non-negotiable for a leak-free system. I also make absolutely certain that the kit is a perfect match for my specific vehicle’s year, make, and model. Brake line lengths and mounting point shapes can vary even between trims, so using a vehicle-specific kit saves a world of installation hassle.
Finally, I consider the finish and any included extras. While a bright stainless steel finish looks great, some manufacturers offer a vinyl coating over the braided steel. This isn’t just for looks; it helps prevent the braiding from trapping dirt and moisture, which can slowly wear it down. It also makes them much easier to clean. A good kit will also include all the necessary washers, crush washers, banjo bolts, and mounting brackets. There’s nothing worse than getting halfway through an install and realizing you’re missing a crucial, specialized little piece. Paying attention to these details from the start means I end up with a brake line upgrade that I can trust for years and thousands of miles.
FAQ
Are AGS brake lines difficult to install?
If you have moderate mechanical experience and the right tools, installing brake lines is a job you can do yourself. The process involves safely lifting the car, removing the wheels, and carefully replacing one line at a time. The most critical part is bleeding the brake system thoroughly afterward to remove all air bubbles. If you’re not completely confident in your ability to do this, or if you don’t have a good brake bleeder kit, I strongly recommend having a professional mechanic handle the installation. Brakes are the most important safety system on your car, so the job has to be done correctly.
What is the main performance benefit of upgrading to braided lines?
The single biggest benefit I notice is a much firmer and more responsive brake pedal. Standard rubber hoses can flex and expand slightly under hard braking, which makes the pedal feel a bit soft or spongy. Braided stainless steel lines like those from AGS minimize this expansion dramatically. This means when you press the pedal, the force goes more directly to clamping the brake pads onto the rotors, giving you more immediate and predictable stopping power, which is especially noticeable during aggressive driving or on a track.
How long do stainless steel brake lines typically last?
A high-quality set of stainless steel braided brake lines is built to last a very long time. While rubber lines can dry out, crack, and deteriorate from heat and exposure over 5-10 years, a well-made braided line can often outlast the vehicle itself. The stainless steel sheath is incredibly resistant to the elements and abrasion. However, it’s still a critical safety component, so I make a point of visually inspecting them during routine maintenance like tire rotations, looking for any signs of damage, wear, or leaks.
Will AGS brake lines improve my daily driver’s braking?
Yes, absolutely. While the difference might be more dramatic on a race track, you’ll still feel a worthwhile improvement in everyday driving. That firmer pedal feel translates to more confidence and control in all situations, from city traffic to emergency stops on the highway. It makes the braking action feel more precise and direct. For anyone looking for one of the best AGS brake lines reviewed for performance and longevity to upgrade their daily driver, it’s a modification that provides a tangible benefit every time you use the brakes.
Do I need to use a special type of brake fluid with these lines?
The brake lines themselves don’t require a special fluid; you can use the same type (DOT 3, DOT 4, etc.) that your vehicle’s manufacturer recommends. However, since you’ll be completely draining and refilling the system during installation, it’s the perfect opportunity to upgrade to a high-performance brake fluid. Standard DOT 3 or 4 fluid absorbs moisture from the air over time, which lowers its boiling point. For better performance, especially if you drive hard, I often switch to a DOT 4 or DOT 5.1 fluid with a higher dry and wet boiling point to prevent brake fade.
