While factory rubber hoses are prone to softening and expansion—especially under the heat and pressure of spirited driving—these 304 stainless steel braided lines maintain their integrity. The smooth-bore PTFE (Teflon) core minimizes expansion, resulting in a firmer, more communicative brake pedal and significantly reduced pedal travel.
Engineering excellence is at the forefront of this kit; unlike universal lines that rely on multi-piece adapters, these are application-specific with the correct lengths and fittings to eliminate potential leak points. Each line is protected by a smoked-clear PVC outer jacket to prevent abrasion and is individually pressure tested to 3,000 PSI to ensure absolute reliability in the most demanding conditions.
Features:
- Consistent Braking Performance: SAE "low-expansion" certified lines provide a firmer pedal feel and faster hydraulic response.
- Premium Materials: Constructed with 304 stainless steel braiding over a smooth-bore PTFE / Teflon core for maximum durability.
- Precision Fit: Application-specific lengths and fittings ensure a perfect plug-and-play installation without the need for adapters.
- Rugged Protection: Smoked-clear PVC outer jacket protects the braided lines from dirt, debris, and friction against suspension components.
- Extreme Pressure Safety: Each line is factory-tested to 3,000 PSI—far exceeding standard automotive braking pressures.
- Certified Quality: Fully DOT-compliant and tested to meet FMVSS106 and SAE J1401 standards.
- Universal Fluid Compatibility: Safe for use with DOT 3, 4, 5 (silicone-based), and 5.1 brake fluids.
