Reverse manual valve body questions

Duane - If you get in contact with Joe, let me know what he says. I have seen the internals of a safe neutral 727 brake and there is more complexity involved by adding the safety valve and transfer plate circuitry compared to a Griner 22G20 or 22G20B brake without the 2nd Neutral.

I have also seen the inside of an older TranzAct clean neutral which basically dumped all pressure after 3rd gear. Maybe Joe has upped his game.

If you feel curious, take apart the TranzAct Nitro Comp brake and trace the circuits. Or take some pictures and send them to me. I will be glad to trace it out.

Now I am even more confused.
Here is a brief explanation from griners instructions.
I have heard transbrakes that require a button to be pushed to get reverse referred to as safety brakes. Griners instruction make it sound like it is the configuration of the brake that allows for safe neutral.
