Brake Booster leaks vacuum

[corey.sherman@rcn.com]

My mechanic claims that my Brake Booster leaks vacuum on my 1971 TR6.

The DPO purchased it from TRF five years ago. I made an inquiry to TRF, 
and they said that they don't sell repair kits for the unit, but would 
sell a new one on sale for $295 (gee, thanks).

   Are these units serviceable?
   Are repair kits available?
   Should I rebuild myself, or is it better to have a "shop" do the work?
   Do I just breakdown and buy another unit?
   Are there any other options?

Any suggestions.
