20in #3 Line -3 Straight/-3 Straight ALL46300-20

OVERVIEW

When you are pushing your air-cooled Volkswagen or custom sand rail to the limits, the last thing you want is a spongy brake pedal or a line failure in the middle of the dunes. The Allstar Performance 20-inch #3 braided stainless steel brake line is the ultimate upgrade for enthusiasts who demand precision and reliability. Unlike factory rubber hoses that expand under pressure and degrade over time due to UV exposure and harsh environments, these high-performance lines feature a PTFE (Teflon) inner core. This ensures that every ounce of pressure from your master cylinder is translated directly to your calipers or wheel cylinders, providing a firm, consistent pedal feel that is essential for both technical off-road maneuvers and high-speed street driving. The 20-inch length is specifically designed for those custom applications where stock lengths just won''t cut it, offering the perfect amount of slack for long-travel suspension setups without risking snags.

Durability is the name of the game in the VW world, and Allstar Performance delivers with a rugged stainless steel outer braid that acts as a suit of armor for your braking system. This braiding is not just for looks; it provides incredible resistance to abrasion from flying rocks, debris, and the constant vibration inherent in air-cooled engines and off-road chassis. Because the inner PTFE hose is chemically inert, it is fully compatible with all types of brake fluid, including DOT 3, 4, and 5.1, preventing the internal "swelling" often seen in older rubber lines. Whether you are plumbing a front-end disc brake conversion on a classic Beetle or setting up a turning brake system on a dedicated woods buggy, these -3 AN straight-to-straight lines provide a professional-grade connection that looks as good as it performs. Don''t settle for "good enough" when it comes to your stopping power; upgrade to a line that is built to handle the heat and pressure of real-world driving.

PRO TIPS

Pro Tip 1: Avoid the "Saw" Effect. Braided stainless steel lines are incredibly tough, but that toughness makes them act like a high-speed saw if they are allowed to rub against other components. Always use insulated P-clamps or zip ties with a section of fuel hose as a buffer to secure the line away from your frame, fuel lines, or wiring harnesses. If the line is allowed to vibrate against a soft aluminum part or a plastic wire loom, it will eventually cut right through it. Proper routing is the difference between a professional build and a future mechanical failure.

Pro Tip 2: Adaptation is Key. Most vintage Volkswagens utilize M10x1.0 metric bubble or inverted flare fittings at the master cylinder and wheel cylinders. Since this Allstar line uses -3 AN (Army-Navy) 37-degree flare fittings, you will need the appropriate adapters to bridge the gap. We highly recommend using steel adapters rather than aluminum for braking systems to ensure the threads can handle the high torque required for a leak-free seal. Always double-check your flare type (bubble vs. inverted) before ordering your adapters to ensure a perfect match.

Pro Tip 3: Mind the Twist. When installing any braided line with straight fittings on both ends, it is very easy to accidentally "pre-load" or twist the hose while tightening the nuts. A twisted hose is far more likely to fatigue and fail or rub against moving suspension components. Always use two wrenches: one to hold the fitting steady and one to tighten the nut. Before final tightening, ensure the hose has a natural, relaxed arc. This is especially important on the front end of a VW where the wheels turn, as you need that 20-inch length to flex freely without binding at full lock.
