I'm in the middle of changing rotors, brake lines and pad to get my E3 ready for the track this spring and cannot remove the uppermost end of the front brake line. A major amount of penetrant has been used to no avail. Is there a secret? I'm afraid that I will break the hard line connection from its screw-on end. What is the correct tool for holding the uppermost connector from rotating with the brake line connector, if any. Is there a method to removing the clip from the sheetmetal mount between the two lines? I am now officially stuck and this is only the first wheel.
