NOW WITH 4 DIFFERENT COLORS TO CHOOSE FROM! Madness stainless steel brake lines improve pedal feel and reduce the amount of time between applied pedal pressure and actual deceleration by preventing expansion, which stock rubber flex lines allow. This provides a quicker pedal response, and allows the driver to maintain consistent brake pressure and precision brake modulation. Brake Lines Construction Madness brake lines consist of a Teflon inner line that is 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. Madness brake lines feature a Clear Abrasion Resistant Cover for maximum protection against chaffing All Madness Stainless Steel Brake Lines are DOT (United States Department of Transportation) compliant and 100% tested to a pressure of 4500 psi. NOTE: MINI Cooper has changed rear brake line designs starting in 4/03. Check your production date before ordering and select the appropriate kit from the drop down menu.
