Well, it happened to me today. 
I was at a BMWCCA autox this morning and during one of my runs I hit the brakes and it was hard as a rock (25mm master cylinder) and I had to push hard as hell to get slow. Originally I thought the vac line had popped out or something, but it's just leaking vacuum. I get a nice hissing noise in the cabin when I get on the brakes.
I'm glad this didn't happen last weekend at Road Atlanta....
PS: This is an iX booster and I'm planning on replacing it with another used one.
