I finally tracked down some brake reservoir seals and they arrived today. I went to the lockup and decided to remove the master cylinder and work on it at home. Now the unions on the pipes that go into the master cylinder is what I'm wondering about. I have a 10mm union at the end furthest from the servo and the one nearest the servo is a 13mm union. So, is this a Ford set up or a LandRover set up?  Thanks in advance, also a big thanks to CS Escorts of Widnes for pointing me in the direction
