Delayed braking
Hey guys, my car developed this odd braking characteristic the other day, every time I step on the brakes there's this hard empty feeling for a second then the pedal sinks down a little bit more and the brakes finally engages, no matter how hard or soft I step on the brake pedal it still happens.. it makes me feel uneasy because when I need to instantly stop IE panic brake the car won't stop instantly... any thoughts?

Here's my thinking. I am just taking at face value that it takes time as described by the OP.
When you're not braking, there is vacuum on both sides of a big diaphragm. When you step on the brakes, you dump air into the back side of the diaphragm, which takes time. The air pushes on the brakes. Normally, this happens fast enough that you don't notice the delay.

I have this same exact issue. It's a hard pedal for just a fraction of a second then it's just fine, although a little slow, the rest of the way down. It takes a little more pedal effort than I'm used to as well which leads me to believe it's a booster problem myself. I know that all the calipers and lines are fine, the only things I don't know for certain are the master cylinder and booster. I'm thinking booster on this one.
