So last week my power brakes went away almost completely. I'm pretty sure I just need to replace my booster, but wanted to double check with you folks in case I'm missing something more simple...

I pulled the one way air valve, and I can blow through, but can't suck back, so I don't figure that's the problem. I do get plenty of vacuum at that line, and if I pinch the hose closed, the idle speed changes...

That's pretty much it, isn't it? Only reason I ask is that I hear no hissing, and this came on very suddenly. In the past, it's been more gradual, and I've usually heard the leak...

thanks
