Metric Steel Brake Line 20 Inches

OVERVIEW

When it comes to your air-cooled Volkswagen''s safety, there is absolutely no room for compromise. This 20-inch EMPI Metric Steel Brake Line is engineered to provide the hydraulic integrity your classic Beetle, Ghia, or Dune Buggy demands. Over years of service, original steel lines can succumb to internal corrosion from moisture in the brake fluid or external pitting from road salt and debris. Replacing these aging components with high-quality, pre-flared steel lines ensures that your braking pressure remains consistent and your pedal feel stays firm. Whether you are performing a complete frame-off restoration or just replacing a damaged section during a weekend maintenance session, this 20-inch segment offers the perfect length for various runs across the chassis or out to the wheel cylinders, providing a professional-grade repair that meets or exceeds original equipment standards.

Designed specifically for the metric systems found in vintage VWs, this line features the essential 10mm x 1.0 thread pitch and the critical bubble flare required for a leak-free seal. Unlike standard double flares used on domestic vehicles, the bubble flare is the industry standard for European braking systems, ensuring a precise seat against your master cylinder, wheel cylinders, or T-fittings. The durable steel construction provides the necessary rigidity to prevent line expansion under high-pressure panic stops, translating every ounce of foot pressure directly to the pads and shoes. Don''t let a brittle, rusted brake line turn a scenic cruise into a dangerous situation; upgrade to EMPI''s reliable steel lines and drive with the confidence that your stopping power is fully optimized for the road or the trail.

PRO TIPS FROM THE SHOP

Tip 1: Use a Proper Tube Bender

When routing your new 20-inch steel line, never attempt to make sharp bends by hand. Hand-bending often leads to kinking, which restricts brake fluid flow and creates a structural weak point that could fail under pressure. Always use a dedicated handheld tube bending tool to achieve smooth, radius curves. This ensures the internal diameter of the line remains constant, maintaining maximum hydraulic pressure and a clean, professional appearance on your chassis.

Tip 2: Verify the Bubble Flare Seat

Before you begin threading the 10mm nut into your wheel cylinder or master cylinder, ensure the receiving port is completely clean of old debris and rust. Since this is a bubble flare design, the seal is created by the "mushroom" head of the line compressing against the seat of the fitting. If there is grit or a leftover piece of an old seal inside, it won''t seat correctly, leading to persistent leaks. A quick blast of brake cleaner and a visual inspection can save you hours of troubleshooting later.

Tip 3: The Importance of a Full System Bleed

Anytime you open the hydraulic system to replace a hard line, air is introduced. Even if you only replaced one 20-inch section, we highly recommend performing a full four-wheel brake bleed starting from the wheel furthest from the master cylinder (typically the passenger rear). This is the perfect time to flush out old, dark brake fluid and replace it with fresh DOT 3 or DOT 4 fluid. Fresh fluid prevents the internal corrosion that likely destroyed your previous lines in the first place, protecting your investment for years to come.
