Craig,

Did they explain why your master cylinder is toast? I am not an originality  
freak, but I much prefer to repair and refresh what is originally there  
than try to work with a part from India ... unless I have to. Master  
cylinders fail through 'expected' wear, mostly, and it is usually to the  
benefit of Apple Hydraulics or Whitepost or similar to execute a re-bore  
using a brass sleeve. The good-as-new re-bored part can then be returned to  
the car. Perhaps there was another failure than normal wear? My local shop  
returns to me anything that comes off the car. Does yours, or did they toss  
it?

TRF still offer the original Girling master cyclinder. I wonder where yours  
came from.

It also sounds like you have a faulty servo. Maybe a valve in the servo is  
sticking. I think it unlikely that you have a on/off vacuum causing an  
as-expected this time; less than expected next time, brake performance.

Parts for the original servo are available, such as here:  
http://www.rimmerbros.co.uk/Item--i-GRID006770. If you could have the  
original returned, you may be tempted to find someone to rebuild it, as you  
say you don't 'do brakes'. The kit by the way, is around $35 and the  
after-market servo is around $350 and it has different internals.
