Brake booster problem?
I put a new brake booster on my truck a couple years ago when it started leaking vacuum. The last few days I noticed an intermittent problem. It's like the brake pedal sticks down and the vacuum is holding it. I lift it up and it's fine, but it sure doesn't feel safe. Could the check valve be bad?

It only did it two or three times in the last few days but I've been driving a lot. I think it did do it with the engine off once or twice. And the pedal seemed to go down far. I'm starting to think the master cylinder might be going.

Yea, the first time it did it I checked the master cylinder and it was a little low. I topped it off and it did it one or two more times but the level is still full. Is it safe to drive it another week?
