2002 325i brake pedal ouestion

when you mash the brake pedal you here a swishing air sound coming out from from under the dash, what could the problem be.

I don't know, maybe your pushing way to hard and putting the pedal all the way through the floor?

Is this new? I used to have the same thing on my E36 328i, but I don't recall if I ever did anything to change that or whether it ever went away. Check under the hood to ensure that the brake fluid reservoir cap is on tight.

Is there a lot of play on the brake pedal, or is it pretty stiff? Stiff is good. Spongy brakes are a sign of air in the system, which is fixed by flushing/replacing/bleeding brake fluid, but I may be looking at this whole thing from the wrong point of view

what about the pressure switch would this cause this, the first thing people say is you have a air leek when they first hear this, it is that loud. No not mashing to hard!

Either the master cylinder or the brake booster going.
