18in #4 Line -4 Str/-4 90 Deg

The 18in #4 Line -4 Str/-4 90 Deg braided brake hose from ALLSTAR PERFORMANCE is a purpose-built hydraulic line designed for custom and high-performance automotive brake systems. Built for mechanics and enthusiasts who demand precision in their brake plumbing, this hose eliminates factory rubber lines in favor of durable, route-flexible stainless steel construction. Whether upgrading a classic restoration, modifying a race car, or installing a custom brake circuit, this hose handles the critical job of delivering consistent hydraulic pressure from master cylinder to caliper.

This brake line features a 4 AN (dash-4) bore with a straight female fitting on one end and a 90-degree female fitting on the opposite end, giving you flexible routing options in tight engine bays or custom frame configurations. The PTFE-lined inner core resists fluid degradation and maintains consistent brake feel over thousands of miles, while the braided stainless steel outer layer provides abrasion resistance and a professional appearance. At 18 inches long with a compact weight of 0.2 lbs, the hose fits easily into most custom layouts without excessive slack or kinking, critical factors in maintaining brake response and pedal feel.

This adapter is ideal for builders working with aftermarket brake components, dual-circuit setups, or frame-mounted master cylinders where standard hose configurations don't fit. The straight-to-90-degree geometry makes it especially valuable when transitioning between perpendicular port locations or when routing around engine accessories. Installation requires AN-compatible fittings on both ends; ensure your master cylinder and brake caliper ports accept 4 AN female connections for proper fitment and leak-free operation.
