Coated Braided Line 48in #4 Hose -4 Str/-4 90 Deg

The Coated Braided Line 48in #4 Hose with -4 Str/-4 90 Deg fittings from ALLSTAR PERFORMANCE is a purpose-built hydraulic brake line for high-performance vehicles, race cars, and custom automotive builds. This 48-inch assembly connects master cylinders, proportioning valves, and brake calipers with reliability that meets the demands of both street and track environments. Mechanics and fabricators rely on this hose when stock rubber lines cannot withstand the pressure cycles, heat exposure, or custom routing requirements of modified braking systems.

Constructed with braided stainless steel reinforcement and a black vinyl protective coating, the Coated Braided Line features a PTFE (polytetrafluoroethylene) inner core that resists fluid degradation and prevents corrosion from within. The 4 AN (AN4) port size accommodates moderate to high flow rates without excessive pressure drop, making it ideal for street machines and entry-level race applications. The straight female fitting on one end and 90-degree female fitting on the other enable flexible routing around engine compartment obstacles—a critical advantage when packaging brake lines through tight spaces or around custom headers and intake manifolds.

This hose assembly works best in vehicles undergoing brake system upgrades, including dual-circuit conversions, proportioning valve installations, and rear-disc retrofits on classic or modified cars. The 48-inch length accommodates most domestic and import platforms, though custom fabricators should verify routing before purchase. Technicians appreciate the vinyl coating for both UV protection and improved aesthetics in show vehicles, while the PTFE lining ensures consistent pedal feel and brake modulation across repeated heat cycles—essential for spirited driving or competition use.
