Installation Notes and Tips

Before installation, ensure the vehicle is securely lifted and the brake system is depressurized. Remove the old brake hose carefully to avoid brake fluid spillage. Use the included gaskets to create a proper seal at the fittings. Since mounting hardware and brackets are not included, retain or replace existing components as needed. After installation, bleed the brake system thoroughly to remove air and verify there are no leaks.
