Um....using standard copper plumbing pipe is a perscription for FAILURE!!!!! Copper pipe is NOT designed to withstand the heavy vibes (relative to household plbg) of an automotive application- steel brake lines, aftermarket tubing or OEM piping designed for THAT application is the only way to go here.....copper should NEVER be used with any pressurized automotive applications.....
