The Goodridge G-Stop rear brake line kit for 2008–2015 Audi S5 replaces factory rubber hoses with a PTFE inner and stainless-steel overbraid to provide a firmer pedal and eliminate sponginess. Intended to improve braking consistency and reduce stopping distances in performance applications, these lines resist abrasion and corrosion while increasing overall braking efficiency.
