I really think it's the brake booster. I'm having the same problems on my 87 325i BMW. I went to a 25mm MC from a 23mm MC and it is solid when the car is off just like mike's car. However, it will drop significantly when the car is started.
(Yes I've bled my brakes just as many times as mike has without change on start.)
Any thoughts would be appreciated.
