We offer OEM replacement brake lines as well as upgraded stainless steel brake lines. We offer OEM replacement brake lines as well as upgraded stainless steel brake lines. Stainless brake lines are a must for any track driven BMW and make a great upgrade on street cars as well. Brake lines should be replaced every few years anyway and braided stainless lines offer an additional layer of protection. Rubber brake lines deteriorate from the outside and inside. The external rubber can become stiff, crack, or get damaged by debris. The stainless braiding and Teflon inner coating help protect the outside of the line from debris. And with a stronger material the line will not expand or swell under extreme braking conditions. Stainless brake lines provide a firmer positive pedal feel under hard braking by greatly reducing the expansion that can be found in stock rubber lines. The internal of old stock rubber lines can become constricted over time even if the exterior looks normal. With a blockage or restriction you can have serious braking issues that often go mis-diagnosed as warped rotors, stuck calipers or bad ball joints. Make sure you don't overlook your brake lines! All brake lines, rubber or stainless, should be replaced every few years and any time you replace a brake caliper.

These are the highest quality stainless brake lines that meet DOT specs at great prices. Our lines are made with stainless braiding and Teflon inner lines. The fittings are the correct BMW type and sizing and with swaged fittings and an additional rubber boot for protection.

Complete set of DOT-compliant lines for an improved pedal feel

ECS Exact-Fit stainless reinforced brake lines provide more confident and dependable stopping by maintaining consistent brake pressure, long lasting corrosion resistance, and increased protection from failure.

Even when new, factory style fabric mesh lined rubber hoses are prone to expansion under the pressure of hard braking, whether it be highway panic stops or threshold braking at the track. This expansion is even more prominent in aged and weathered rubber hoses. ECS Tuning's Exact-Fit lines are engineered and assembled with braided stainless steel mesh and offer superior expansion resistance and reinforcement. The resistance to expansion creates a firmer pedal, and a more direct pedal feel. The signature red polymer coating provides additional protection from the elements and abrasion common with the constant movement of suspension and braking systems.

ECS Exact-Fit brake lines are engineered in house to comply with DOT (U.S. Department of Transportation) FMVSS 106 standards. All lines are made on dedicated, DOT-compliant brake equipment and each is tested to 3,000 psi before being shipped.

Included in this kit are a pair of custom made ECS Exact-Fit brake lines for the front and rear of your vehicle,
