StopTech Stainless Steel Braided Brake Lines provide a faster, firmer, more uniform pedal response by maintaining constant brake pressure. Additionally the Stainless Steel lines provide precision brake modulation especially during the braking threshold. The improvement in pedal feel is most dramatic on older vehicles where the rubber line may have softened and swelled due to factory age. StopTech Brake Lines consist of a PTFE (commonly referred to as Teflon) inner line that carries the brake fluid which is then covered with a layer of stainless steel braided fabric. The PTFE tube is highly resistant to expansion under pressure and will not degrade from exposure to brake fluid. The stainless steel braiding provides support for the PTFE and the fabric is extremely durable against incidental impact and abrasion. Next Stainless Steel Braided Hose is jacketed with a clear abrasion resistant PVC cover for maximum protection against galling and features strain relief devices, reinforced end fittings. A variety of end fittings are available to meet most application needs. All parts are designed for proper fit and durability. All necessary brackets and fasteners are included with every line kit. Every StopTech brake line is 100% internally tested to a pressure of 4,500 psi. This is almost 4 times the typical line pressure exerted by a production vehicle master cylinder. StopTech is a registered brake line manufacturer with the United States DOT and all StopTech stainless steel brake lines are manufactured to meet DOT compliance standards. StopTech stainless steel lines also meet or exceed FMVSS 106 and applicable International and EU standards.
