Goodridge G-Stop High Performance Brakeline race-bred street brake lines are constructed from the finest quality hose, consisting of a PTFE inner hose covered by braided stainless steel. In addition to providing a more responsive and firm brake pedal by eliminating the “spongy” feel that often accompanies stock rubber brake lines, G-Stop High Performance Brakelines are abrasion and corrosion resistant to stay good looking for a long time to come.
