R1 Concepts Front Stainless Steel Brake Lines for 2009-2016 Audi A4 (HSK-73017)

Fits 2009-2016 Audi A4 (Front).

R1 Concepts Stainless Steel Brake Lines (HSK-73017) are engineered to replace soft factory rubber hoses, eliminating the line expansion that causes a spongy pedal. This upgrade provides a firmer, more responsive brake feel and more consistent hydraulic pressure, essential for spirited driving, towing, or heavy-duty use. The lines feature a high-performance PTFE inner core wrapped in a high-strength stainless steel braided weave for maximum pressure resistance.

To ensure a long service life and protect against the elements, each line is finished with an abrasion-resistant clear PVC outer coating that shields the braid from dirt, debris, and corrosion. These lines are United States DOT approved, meeting strict safety standards for street use while offering performance-grade durability. Precision-engineered fittings ensure a direct-fit installation into factory mounting points.
