The Goodridge G-Stop rear brake line kit for 2004–2013 Mazda 3 replaces stock rubber hoses with a PTFE inner and stainless-steel overbraid to provide a firmer pedal and remove sponginess. Designed to improve braking consistency and shorten stopping distances in performance applications, these lines resist abrasion and corrosion while increasing overall braking efficiency.
