How hard is it to remove the stock brake lines on a C5 and replace with braided lines? Will I be needing any special tools?

Other than the right wrenches you should be fine, the new lines come with the new crush washers right?

Yes they do come with new crush washers. And the lines are very easy to install.

The hardest part will probably be bleeding them.
