Coated Braided Line 36in #3Hose -3Str/-3Str Steel

The ALLSTAR PERFORMANCE Coated Braided Line 36in #3Hose -3Str/-3Str Steel is a purpose-built hydraulic brake hose designed for high-performance automotive applications where reliability and durability are non-negotiable. Whether you're building a custom hot rod, upgrading a track car, or restoring a classic vehicle, this 36-inch braided brake line delivers the precise hydraulic response and robust construction that separates amateur installations from professional-grade work. Mechanics and enthusiasts rely on braided stainless steel brake lines because they resist expansion under pressure, maintain consistent pedal feel, and eliminate the sponginess associated with rubber hoses during hard braking or extended track sessions.

This hose features a black vinyl-coated braided stainless steel construction with PTFE (polytetrafluoroethylene) inner lining—a combination that excels in demanding environments. The stainless steel braiding resists corrosion and provides structural integrity against high brake pressures, while the PTFE lining ensures compatibility with modern brake fluids and eliminates the swelling issues that plague older rubber lines. Both ends terminate in -3 AN straight female fittings, allowing direct connection to standard -3 AN male ports found on custom brake proportioning valves, master cylinders, and wheel cylinders. The vinyl coating protects the braided layer from UV degradation, moisture intrusion, and abrasion during routing through engine bays, chassis tunnels, or tight suspension geometries.

This 36-inch hose is ideal for custom brake line installations on street rods, race cars, vintage muscle cars, and fully independent suspension builds where factory routing no longer applies. The AN fitting standard ensures compatibility with a vast ecosystem of performance brake components—from custom master cylinders to adjustable proportioning valves and track-proven wheel cylinders. Installation requires proper hose routing away from heat sources and sharp edges; secure support clamps every 12–18 inches to prevent vibration-induced fatigue. For builders running DOT 4 or 5 brake fluid in high-temperature environments (road racing, drag strips, or autocross), this PTFE-lined configuration outperforms rubber by maintaining consistent modulation and eliminating fade-induced pedal travel creep that can compromise stopping distance.
