Check the condition of the 3" braided rubber hose that's between the vacuum pump and the servo Sean.....
I had a similar problem with mine and this was the issue. If it looks slightly flat in the middle change it.......mine looked like this after I cut the braiding back, two 30mm splits on opposite sides of the pipe. Any damage won't look obvious until you cut away the braiding.
