I've worked it out, I downloaded the shop manual, but you have to change you brake fluid at the same time and I'm in the middle of my exam week so I am waiting
It shouldn't be too long though, and I am expecting my motor any day now so we'll see how I go.
My aim is to finish by the end of the year (our summer) but I have a lot of money to save up for the batteries/BMS/charger. Everything else is should go pretty easily.
