Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before beginning brake hose replacement. Carefully remove the old hose, noting the orientation of the female and male threaded fittings (M10 x 1.0). Avoid twisting or kinking the new hose during installation to maintain flexibility and integrity. Use appropriate brake fluid and bleed the brake system thoroughly after installation to remove air and ensure optimal brake performance.
