308130 / 12222 - Application Notes Stainless Steel Brake Lines. Each time you apply pressure to the brake pedal to slow your car, some of the hydraulic energy is wasted expanding the stock rubber brake lines. Effective braking power is decreased. This is also the cause of the soft feel some cars exhibit at the brake pedal. As the lines age, the softness increases. This "line swell" can be eliminated or greatly reduced with the use of high quality stainless steel brake lines. When combined with cross drilled rotors, high performance brake pads and high quality brake fluid, the difference in stopping power and brake feel is impressive. These lines are stainless steel braided, Teflon brake line hoses that are certified by an independent testing lab and meet D.O.T. specification FMVSS-106. Each and every brake hose is pressure tested before it gets packaged and each and every brake hose comes with a limited replacement warranty. One of the only stainless steel braided brake lines legal for sale and use on street driven vehicles throughout the world with D.O.T., TUV and JWA testing requirements all fulfilled.
