Ok, I have the entire Master Cylinder off and apart. I do not see any residual pressure relief valve. The only spring I have found is the main piston return spring. This spring has a little valve on the end of it with a rubber diaphragm inside of it's housing. It appears that it only allows fluid to go through it one way. Therefore I am unsure of how any pressure could ever be released off the breaks. As I said before I am very new to fork lifts and motor components. I am mechanically inclined but don't see any other way of putting this back together. I have looked at images online of similar products and i feel I have the orientation correct. However, A diagram or walk through would be much appreciated. Thanks again for all the help.
