Just purchased some second hand Hynautics controls for less than 10% of new price
and have given them a clean up and they all appear to be in good condition underneath the old paint
I have the fluid reservoir to clean up today and am wondering if there is anything I should be doing to them before installation
They all seem to be tight and smooth, no wobbles, positive sucking sounds when levers and actuators are moved.
Is there anything that needs service
or replacement apart from lines and "O" rings, before installation
