I have the same issue in my 54 plate Hawkeye WRX Waggon with Brembo big discs and calipers. Its not speed related but does appear to be turbo boost related - if I go from boost quickly to brakes, the pedal servo doesnt seem to work - like its pressurised instead of vacuumed.
This was occuring before I replaced the rubber brake vacuum pipes with silicon hose and I didnt see any non-return valve that i may have removed. It also tends to stall on final stopping at a junction with the result of loosing all vacuum - and brakes!!!!
As soon as a quick release and re-apply of the pedal happens, the brembo's stop it on a sixpence - but soon that wont be in time i'm guessing...
Any help appreciated... Cheers.

inside the pipe. Remove it and fit into your
new silicone pipe and all will work again as it should. If it was the same before the pipe was replaced and its definatly not in the old pipe then your gonna need to get one
