Hi all,

I just installed a rebuilt hydrovac on my 48 2 ton from my local NAPA.I understand you have to put some kind of oil in the booster.What kind of oil and where on the unit do you put it in?I got no instructions with the unit.Also what kind of oil do you run in the brake system itself (master cylinder and lines?) I have new brake lines a rebuilt master cylinder and wheel cylinders.

Thanks!!
