Because you "HAVE" to press the brake pedal , prior to
pressing the start button :
sometimes it's squish (Normal Power brake pedal)
sometimes it's HARD (But after it starts, it turns to squish)
Does this mean I have a vacuum leak,or possibly a check valve
is faulty, or needs cleaning ?
Thanks in advance.

Mine does this too at times, guess I'll see what the experts have to say.

Re: Brake Pedal
This sounds like normal operation. Mine does this, too. I suspect you'll find the longer the car sits after being shut off, the harder the pedal is to push.
