(Front -) Built for the (08-10) Audi S5... StopTech Stainless Steel Brake Lines provide a quicker pedal response, maintaining consistent brake pressure and precision brake modulation, especially during threshold braking. All StopTech Stainless Steel Brake Lines are manufactured to meet DOT Compliance Standards, and every line is 100% tested in-house to a pressure of 4500 psi. StopTech brake lines consist of a Teflon inner line, which is then covered with a layer of stainless steel woven braid. The Teflon tube is very resistant to expansion under pressure and will not degrade from exposure to brake fluid. The stainless steel braid provides support for the Teflon and the weave is extremely durable against incidental impact and abrasion. Finally, StopTech brake lines are coated with a Clear Abrasion Resistant Cover for maximum protection against chaffing. All necessary brackets and fasteners are included with each line kit. Adding a set of StopTech Stainless Steel Brake Lines to your performance vehicle will provide an immediate improvement to brake performance and pedal feel from the very first stop. All StopTech Stainless Steel Brake Lines are DOT (United States Department of Transportation) compliant and 100% tested to a pressure of 4500 psi.
