Q: Can I install these brake lines myself?

Professional installation is recommended. Replacing brake lines means opening the hydraulic system and then bleeding it properly with fresh high-temp fluid, which is not a job to rush. The laser-cut brackets make routing straightforward because they match the factory points, but if you are not confident bleeding brakes, have Unplugged Performance in Hawthorne or an authorized installer do it. A trapped air bubble undoes the benefit of the upgrade.
