I'm pretty sure my booster is bad.

So I'm pretty sure my booster is bad, this is whats going on:
I have stopping power but not until the pedal is near the end of the stroke. Its nothing until that point. When the car is running, its zero resistance until about 2" from the floor. Then I have full brake feel (no spongy feel). When the car is off (no vacuum) it feels like i'm pushing through the brake booster, its spongy and then there's a a sort of pop feel (not sound) and then it hits the brake pressure.

Can anybody confirm this as a bad booster?

kick brake pedal then turn on the engine
if the pedal down a bit, your booster fine
and if the pedal still that position, your booster bad

I aware or what your suggesting and its the first thing I thought of. Something is definitely up.

I know it doesn't help but I am having the same problem almost exactly, I to think its the master but it cost to much for a hunch. Lol. It's that or maybe the master.

A bad booster would manifest as the exact opposite; a very hard pedal with no stopping power.

Figured it out, had a bit of moisture in the passenger front line. Replaced the master, reservoir grommets and cleaned the res. Flushed with fresh brake fluid. Bought speed bleeders for this car like all my past ones. The bleeding job took no time at all. Everything is back to 100%.
