Digging up an old thread here...
When the car starts, the pedal is very stiff and not very effective (I'm guessing no boost assist). After a few seconds (I haven't timed it, it could be 10-20) braking is back to normal. This has happened twice in the past week, but not the other five days that the car has been started in that week's time.

Is it safe to assume that the booster is fine but I might have a leaky check valve? Is there a way to check the booster for leaks? I suppose I can try checking the check valve with a mityvac and some creative fittings. I'd much rather replace the check valve.
