They are actually air/water. The piston is full of water and the 
reservoir is about 1/2 full. I think it's more like 50/55# air pressure 
to make it work right.

I've redone the ones here as the hoses wear out/degrade and leak out the 
water. The rubber lining breaks off and clogs the entry to the piston. 
It's fun(?) taking everything apart, flushing out the piston, replacing 
the hose and clamps, then refilling the piston and reservoir.  The 
hardest part of the process is getting water back into that tank. (I 
remove the bicycle valve core then use a 20cc syringe with a #18 needle 
and inject the water that way) Anybody have an easier way, I'm all ears!!
