Hi Ruairidh and all,
For once maybe I'm able to give some useful advice here. That will be a first!
I did three times a cable to hydraulic conversion on cars so I've some experience. At least I can tell which mistakes I made.
The choice of master cylinder is very good because those Girling exist in different bores so you can later change if the first choice happen to be wrong.
Then as was emphasized above two things are very important:
The lever effect ie pedal axle to foot versus pedal axle to master cylinder push arm. Better to be able to modify that later if needed.
The rigidity of all the apparatus is incredibly difficult to achieve. Is as better to have the pedal and the master cylinder bolted on the same solid metal contraption and the whole rigidly fixed on the chassis. We are speaking hundreds of kilos of force applied here.
Sorry if my english is not really up to the task!
