I probably would'nt say this type of fault is common that I am going to write about, but using the exact wording of the testers manual, the leak is not covered.
I tested a Vauxhall Omega petrol today, the brake servo really made a loud sucking noise when the engine was turned off. I said must look close at that when I do under bonnet checks?
The manual says;
Check Brake Servo for;
leaks with reference to (3.6D.1f)
I read the manual carefully and said surely if a pipe is leaking because of part is missing, like a vacuum take off, then it should fail?
A vacuum pipe can only be failed if that pipe is deteriorated, kinked or split, collapsed or excessively chafed?
Where is the leak in the pipe, in the split part, but what happens when the pipe is not split, but a take off is missing?
The reason for rejection (3.6D.1f) to my mind is very specific to the servo leaking, and not any other parts?
How would you interpret the rule?

Check for leaks* in any part of the braking system with and without the brakes being applied. Reason for Rejection 1. A leak* in any part of a braking system. * does not specifically mention air, fluid or vacuum

Thanks for that Admin, very much appreciated. I always used that part of the regulation for failing hydraulics, never thought about using it for Vacuum Leaks? This is just the type of reasoning why I like these forums because some other professional will always be able to share an idea that in another persons mind they may not think about it the same way. I have made a note in my testers manual to remind me next time I see this type of problem. Thanks Admin Daveg
