geez it feels like its all slowly coming together now, i have just finished working on the handbrake which isn't finished, but it now works.
back on page 2 of this thread you can see the handbrake i welded into the floor which was from a commodore, so i wanted to use all the commodore brakes (VN rear discs) aswell as the handbrake cable if possible. I didn't think about the problem i would have when i welded the handbrake into the floor, but oh well, some time lying under the car thinking got a good solution sorted.
the problem with the commodore setup is that it has a two piece tailshaft and as a result of that the handbrake cable can go under the front of the tailshaft without any problems - unfortunately that wouldn't work in my case .... but being that the commodore handbrake cable is a bit too long anyways means that i can change its route slightly so now on the drivers side it goes from the wheel up into the diff arch and across the top of the diff then it comes out on the passenger side in the right spot to allow the cable to connect up to the lever properly.
pic below of the cable where it will be secured to go above the diff
some custom brackets to secure the cable under the floor and viola!
so in the above pic you can see the cable that is near the top of the picture is the drivers side cable which has come across the diff, so its a bit shorter, i then located the passenger cable to be in such a spot that the cable is able to be tensioned properly.
so the handbrake works fine now and the screw to adjust it is about in the middle of how far it can go - and the best bit about it is that its all off the shelf parts used from a VR Commodore!
i've also got the new flaring tool die so i have been able to run the rear brake line up to the booster, so thats the entire rear brake system done, i have been looking at the fronts and scratching my head a bit at the moment as im not sure the best place to route the flexable brake line with the hopper stoppers twin piston setup, but once i work that out i will be able to make the front brake lines then that will be all the brakes done!
