Goodridge G-Stop brake line kit for 2015–2018 Audi A3 (diesel) replaces OE lines with a PTFE inner hose and red stainless-steel overbraid to restore a firmer pedal and more decisive braking. The PTFE core and stainless braid reduce sponginess, resist abrasion and corrosion, and improve braking efficiency and consistency for daily driving and heavier use, helping provide shorter stopping distance and steadier modulation.
