Scott Ward: I bought a new Hydravac at the local NAPA store. It seems these things are pretty common. Just a thought about the dissappearing brake fluid some folks have refered to. I don't know if it would have anything to do with it, but the instructions that came with the new Hydravac called for some light oil being put in the unit before using it, and perodically after that. I didn't understand that and had the store owner call the supplier. It seems the one I have has leather seals in it, and the oil is to keep them soft. I'll bet no ever does that. I know I would not have thought of it. I still don't have my brakes working. I have been involved with getting the motor back together and have let the brake issue slide. Will have to get back to that soon. Thanks Allen
