Q: Bike i am getting has Disc on the front a V-type on the back. Would i be able to change the back to disk as well?
A: It depends on whether your bike frsm has disk mounts or not ? also chances are you will have to change the back wheels hub to accomodate the disk itself. To tell if teh rear of your bike is compatible there should be two holes drilled in to what looks like a sticky up piece of metal, near the centre of your rear wheel on your frame.
