    Hi guys. Im fitting vn discs to a fc holden. Ive bent up the 3/16 steel lines and trying to find out the size of the front and back tube nuts that screw into the flex lines?
    Cheers

    wow. Anything will be an improvement on the standard FC brakes. I don't know the size you are after but the other consideration is the flair on the end of the lines. It changed between the VN and VP. Obviously you have made up some lines so don't know what you will have but it will affect how easily it seals. Are you using the VN V8 rotors on the front and what MC and booster are you using?

    Take your caliper to a brake place and buy the nuts that suit and do the same for the MC if you need those ends as well.
