Goodridge G-Stop Stainless Steel Brake Lines will increase pedal feel, and braking force. Rubber lines expand when you hit the brakes, effectively increasing the volume of your brake system and cause an increase in pedal travel and decrease in force. Stainless steel lines don??t expand, plus they protect the lines from damage, and give a high performance look to you car. Goodridge Stainless Steel Brake Lines consist of a Teflon inner brake 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 impact and abrasion. Plus the stainless braid looks great. Goodridge is also the official supplier of Brembo Big Brake Kits.
