Once the engine started the brake pedal went back to being normal, but harder to press first time before engine started. I suddenly got the thought that the brake vacuum reservoir might have got a leak or one of the pipes, so I had a look around and got lucky straight away. The pipe that supplies vacuum from the tandem pump goes up to a disk looking valve with a smaller pipe that leads away to the bowels of the engine bay. The pipe from the other side of the disk valve to the brake booster had a huge crack where it went onto the valve end.
I replaced this entire plastic pipe which had become hard and brittle with a new rubber pipe from supercheap and problem solved.
