I have a Case / David Brown 1690 tractor. A year ago the clutch master cylinder got to where it was leaking badly. I rebuilt it with a kit and it did fine for a while but now is leaking worse than ever. I got a new unit to replace it with. Here is my problem. A year ago I went all over our town trying to find mineral oil and no one had a clue what I was talking about. I even went to the local Case IH dealer and he said we just put universal hydraulic fluid in them and they are fine. Is this true or do I need to try harder and find some mineral oil. Dont want to ruin this new one. Thank you.
