So... What on earth is a POS PDWA valve? Too many initials that I don't know
what they stand for!
Nolan - I had to push the pistons back in a little to remove the pads, in order
to grind off the excessive metal. The moved quite freely, and re-applying the
brakes should have pushed them back to the new correct position. No sign of
any fluif loss around the pistons. So I doubt that is the problem.
In fact, driving home yesterday, I felt that the brakes HAD improved somewhat
compared to how they were at the beginning of this saga. So, the grinding of
the pads and/or the extra bleeding has helped. They are still not quite where
I would prefer them to be, but good enough to lend Daffy to my wife while I
take her car in to have its suspension fixed (it's a Citroen, their suspension
systems are way too complicated for their own good...). I'm hoping that
adjusting the rear brakes will be enough to get the brakes right back to where
they should be, although I may still replace the rubber hoses with new, steel
braided items, to improve response further.
I am confident the my front brakes are still working, at least after the second
press, as they will lock up happily when hit hard. Also, if it was just all
air in the system, I should hear it rushing out under 21 psi pressure from the
tyre, not the complete lack of anything I got when I opened up the bleed
valve. It must be a blockage, which I will try to clear under pedal pressure.

I don't know if anyone has suggested this,,,,
It might be that POS PDWA valve !
If your getting nothing from the front bleeders it just might be that damn
I suggest removing it and throw it as far as you can
