How do you change a brake pipe on the xsara Picasso?

To change a brake pipe on a Citroën Xsara Picasso, first, ensure the vehicle is safely lifted and supported. Release the brake fluid pressure and disconnect the old pipe by removing the fittings at both ends using appropriate tools. Replace it with a new brake pipe, ensuring all connections are secure and leak-free, and then bleed the brake system to remove any air. Finally, check the brake fluid level and test the brakes before driving.
