Did the PTO brake work when the clutch was first rebuilt?
I know the power director valve has two test ports so you can check pressure on both sides (high and low). I don't recall if the PTO valve is the same. It would be good to make sure both sides(clutch and brake) are maintaining pressure.
If they are, all I can say is warped plates, and/or bad brakes.

hydraulic flow is thru pto control valve then to power director. pto has one test port. power director control valve has two. post rebuild everything worked aok. i guess i will have to check pto plates. i am trying to stop pto shaft turning without any load (unhooked) from tractor. should it be able to brake and stop by itself unattached by adjusting control rod ?

The brakes should certainly be able to stop the clutch. However they will not overcome warped plates. The important thing about adjusting the valve is to get pressure both on the clutch, and the brakes.
I recall a new 200 where the power director couldn't be adjusted to get pressure on both high and low. I had to "customize" the quadrant. I don't ever recall that being an issue with the PTO. But I would certainly check to be sure you can maintain pressure on both the clutch and brakes.
