I have had two instances of the rubber brake hoses swelling & the lines become so restricted they act like a valve.

I have had this happen to a GMC and a White.
It kept me looking for the problem for ages & the first time it cost me an unnecessary brake rebuild.

It may be worth a check - especially after 12 years.

Rob.

Thanks, sounds logical but doesn't explain why release the pressure at the bleed nipple doesn't release the shoe tension
