As for maintenance, regularly check the lines for any signs of damage like cuts or leaks. If you notice any issues, replace the line right away. Also, keep the lines clean to prevent dirt and debris from causing abrasion. When driving, be aware that these lines offer a more direct braking response compared to the factory rubber lines, so you may need to adjust your braking habits slightly at first.
