1/4in Brake Line 20ft Stainless Steel

The 1/4in Brake Line 20ft Stainless Steel coil from Allstar Performance is engineered for builders and mechanics who demand reliability in high-performance brake systems. Whether you're custom-fabricating a modified street rod, building a competition vehicle, or replacing worn factory brake lines with an upgrade, this stainless steel option delivers corrosion resistance and longevity that standard steel cannot match. The 20-foot coil length provides flexibility for custom routing through engine bays, chassis tunnels, and frame rails without unnecessary splices or weak points.

Constructed from 304-grade stainless steel, this brake line resists rust and corrosion in harsh underbody environments where moisture, road salt, and thermal cycling degrade conventional steel lines. The 1/4-inch nominal diameter accommodates most domestic and import brake system configurations without requiring adapter fittings at the caliper or master cylinder. Stainless steel maintains its structural integrity under repeated brake pressure cycles—critical for vehicles experiencing track duty, towing, or aggressive driving conditions where brake fluid temperatures climb significantly. The coil form allows you to bend and route the line precisely to your frame geometry, minimizing stress concentrations and ensuring clean installation without kinks that reduce flow or compromise braking response.

This product suits custom fabricators, hot rod builders, vintage car restorers, and motorsport enthusiasts who prioritize brake system durability over stock-replacement simplicity. The 20-foot length is ideal for complete system rebuilds where you terminate both hard lines and flex hoses at your chosen junction points—master cylinder, proportioning valves, and wheel corners. Installation requires standard 37-degree JIC fittings and basic line-bending tools; measure twice before cutting to avoid waste from the generous coil stock. Compatible with all standard brake fluid types (DOT 3, 4, and 5.1) and suitable for road cars, track vehicles, and competition applications where brake line integrity is non-negotiable.
