Goodridge G-Stop brake line kit for 2013–2017 Audi S7 replaces factory hoses with a PTFE inner liner and red stainless-steel overbraid to firm pedal feel and sharpen braking control. The PTFE core and braided stainless construction reduce sponginess, resist abrasion and corrosion, and increase braking efficiency and consistency, delivering more reliable stopping performance under repeated or spirited use.
