Bad rear brakes

[Dragon Slayer]

That is not really a good spot to measure and not sure what it would tell you. I am still in favor off halving system to check.

I do think we need some pictures of what your working with. There where few setups used. Early 70 B and E used a 3 piece set up. Later they moved to a 2 piece and finally a 1 piece block assembly for control. The distribution block on 70B would be spring loaded and return to center after a failure, and again it would trigger a brake warning light. I don't think you ever answered that question I asked several post ago. SPECIFIC symptoms and indications matter.

Issue RESOLVED!!
Ok so iwe finally got around to uppdating this thread
What it boiled down to was,
A faulty prop valve!
Since it was brand new fr.o.m. The Box it must be fabrication error as i see it,
I tried with a new adjustable one, and What i difference
the breakes where suddenly there!!
I had to set the valve to maximum closed to get decent breakes and not Locking upp!!
Now it's just of to the m.o.t to get the verdict)
Fingers crossed Should be fine
The lesson for me, newer trust a part not to fail, even if it comes from a box.
