For more information, visit www.P65warnings.ca.gov.The APR Braided Stainless Steel Brake Lines (BRK00047) are a premium performance upgrade for VW and Audi PQ35 platform vehicles. This kit replaces the factory rubber lines—which are prone to "ballooning" and expansion under pressure—with high-strength 304 stainless steel braided lines. By utilizing a smooth-bore PTFE (Teflon) core, these lines virtually eliminate hose expansion, providing a firmer brake pedal, more consistent modulation, and reduced pedal travel during aggressive driving.
Unlike universal "one-size-fits-all" kits that require adapters, APR’s PQ35 lines are application-specific. They feature the exact length and fittings required for a leak-free, 100% plug-and-play installation. To ensure long-term durability, the lines are encased in a smoked-clear PVC outer jacket to prevent the stainless braid from abrading other components, while every individual line is pressure tested to 3,000 PSI before leaving the facility.
Features:
- Firmer Pedal Feel: Low-expansion PTFE core ensures hydraulic pressure is sent directly to the calipers rather than expanding the hose.
- Superior Construction: Braided 304 stainless steel and Cr3+ steel connectors provide immense strength compared to OEM rubber.
- Application Specific: Designed exactly for the PQ35 chassis with the correct hose fittings to eliminate potential leak points found with adapters.
- Extreme Pressure Tested: Tested to 3,000 PSI—well beyond the typical operating pressures of any street or track vehicle.
- Certified Safety: Fully DOT-compliant; meets or exceeds FMVSS106 and SAE J1401 standards.
- Fluid Compatible: Works with all DOT 3, 4, 5 (silicone), and 5.1 brake fluids.
- Made in the USA: Manufactured with high-quality components and includes new copper crush washers for a fresh seal.
