For more information, visit www.P65warnings.ca.gov.The APR Rear Braided Stainless Steel Brake Lines (BRK00048) are a premium performance upgrade for VW and Audi PQ35 platform vehicles. By replacing the factory rubber lines—which are prone to softening and expansion under high-pressure scenarios—with high-strength 304 stainless steel braided lines, these upgrades provide a significantly firmer and more consistent pedal feel. The smooth-bore PTFE (Teflon) core virtually eliminates hose "ballooning," ensuring hydraulic pressure is delivered instantly to the rear calipers.
Unlike universal brake line kits that rely on multi-piece adapters, these are application-specific, featuring the exact lengths and fittings required for the PQ35 chassis to eliminate potential leak points. Each line is protected by a smoked-clear PVC outer jacket to prevent abrasion against suspension components and is individually pressure tested to 3,000 PSI, ensuring absolute reliability for both street and track use.
Features:
- Firmer Pedal Feel: Low-expansion PTFE core reduces pedal travel and provides precise braking modulation.
- Direct-Fit Engineering: Application-specific lengths and fittings ensure a perfect plug-and-play installation without the need for adapters.
- Superior Durability: Braided 304 stainless steel and Cr3+ steel connectors offer immense strength compared to OEM rubber.
- Extreme Pressure Safety: Every line is tested to 3,000 PSI—far exceeding standard automotive braking pressures.
- Independently Certified: Fully DOT-compliant and lab-certified to meet FMVSS106 and SAE J1401 standards.
- Fluid Compatibility: Safe for use with all DOT 3, 4, 5 (silicone-based), and 5.1 brake fluids.
- Protective Jacket: Smoked-clear PVC coating with red anodized inserts provides a high-end look while protecting the stainless braid from debris.
