I am replacing my brake lines as we speak and I am wondering how the rubber brake line comes off? And has anyone done the goodridge brake lines on theres. Why did they send me 6 brake lines in the kit?

 

a little assistance would be appreciated. I had to leave the Audi in the shop. The bracket for the wheel speed sensor and the brake line I had to take off because the l=brake line to the caliper was seized on. I cut that line and am in the process of making another one. Any assistance would be appreciated.
