For more information, visit www.P65warnings.ca.gov.The APR Braided Stainless Steel Brake Lines (BRK00050) are a high-performance, direct-fit upgrade for the VW and Audi MQB platform. This kit replaces the factory rubber hoses—which are prone to expansion, softening, and "ballooning" under heavy use—with aerospace-grade 304 stainless steel braided lines. By utilizing a smooth-bore PTFE (Teflon) core, these lines significantly reduce expansion, delivering a firmer brake pedal, more consistent modulation, and reduced pedal travel during aggressive driving or track sessions.
Unlike universal brake line kits that rely on prone-to-leak adapters, APR’s MQB lines are application-specific, featuring the correct lengths and Cr3+ steel connectors for a perfect plug-and-play fit. Each line is encased in a smoked-clear PVC outer jacket to prevent the stainless braid from abrading nearby suspension components. Every individual line is pressure tested to 3,000 PSI, ensuring reliability that far exceeds standard operating conditions.
Features:
- Firmer Pedal Feel: Drastically reduces line expansion compared to OEM rubber, resulting in more immediate braking response.
- Premium Materials: Braided 304 stainless steel with a smooth-bore PTFE core for maximum durability and heat resistance.
- Leak-Free Design: Application-specific connectors eliminate the need for adapters, reducing potential failure points.
- Extreme Testing: Tested to 3,000 PSI; certified as SAE "low-expansion" lines (only 0.11 cc/ft @ 2,900 psi).
- Fully Compliant: DOT-compliant and meets FMVSS106 and SAE J1401 safety standards.
- Fluid Versatility: Compatible with all standard brake fluids, including DOT 3, 4, 5 (silicone-based), and 5.1.
- Corrosion Protection: Features Cr3+ steel connectors and a protective PVC jacket with attractive red anodized inserts.
