Brakes not working after sitting over a year.......

So here is the situation.

As many know my car has been sitting since June last year (2013) when the cam went bad and ruined my engine.

Well it's all rebuilt and upgraded and I have finished everything but tuning.

By all indications I should be able to drive it nicely to the tuners.

So I fire it up and want to check that it's good to go and drive it around the block. Get to the end of the driveway and it's got little to NO brakes. Was in reverse so I got it stopped but barely. Had light brakes until the pedal would go no more. (NOT floorboard but a solid hit plenty above where I know it COULD go)

I pull back up and seems like even less brakes. (I put a bigger cam in it than previous and 1st gear is stronger)

No engine codes as far as booster sensor.

So here's what I've checked.....

There are no leaks. Pedal stops solid and does not go any further anyway.

Fluid is full.

Brake booster is hooked up to vacuum.

Sensor is hooked up properly.

So could my caliper pistons be rusted shut?
Could it be the brake booster valve stuck?
Could I be in the twilight zone?


Everything went together well but this is the first hurdle I've faced. I WANT MY CAR BACK.
