Goodridge G-Stop stainless steel brake lines for the Mercedes S-Class (W221) replace OEM rubber hoses with PTFE inner tubing and stainless overbraid to sharpen pedal response and reduce sponginess. The upgrade improves braking efficiency and consistency under demanding conditions while resisting abrasion and corrosion. Kits ship with front and rear lines plus adapters and hardware for a direct-fit installation on supported models.
