Hear air when I step on brakes... Sign In

Have a 87 full size blazer, 305ci, 4x4. Last week my brakes started going to the floor. No leaks and I wasn't losing brake fluid. Someone told me to replace the master cylinder, I did that, pedal really isn't that hard. Everytime I step on the brakes, I hear a burst of air under the dashboard where the brake pedal is. It sounds like someone is letting out a big exhale everytime I hit the brakes. Can't remember if this sound was there before or not. Should I be hearing a sound like that?

I don't think the power booster could be shot. If the power booster went, wouldn't I have a very hard pedal, not a soft one?
