Replaces all four factory rubber brake lines with stainless braided lines for firmer pedal feel, more consistent stopping under repeated hard use, and protection against age-related rubber line failure. Includes all OEM-replacement adapters and banjo bolts needed for direct install.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eFactory rubber brake lines expand under hydraulic pressure, which means some of your brake pedal travel goes into stretching the line instead of actually clamping the calipers. The result is a softer pedal and longer stopping distances under repeated hard braking. Stainless steel braided lines have a non-expanding inner liner wrapped in stainless braid, so every bit of pedal pressure transfers directly to the calipers. Firmer pedal, more consistent feel during repeated track or autocross stops, and the lines don't degrade with brake fluid contamination or age.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Installation Notes\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eProfessional installation recommended.\u003c\/strong\u003e Brake line installation is safety-critical work.
