It is a round metal case that mounts to the fire wall and the master cylinder mounts to it. It has a diaphragm that uses vacuum to assist the brake pedal pressure allowing it to be applied with less pressure, calling it power brakes.

So can it cause the car not to start

Not that I can think of. Plug the vacuum line going to it and see if it makes a difference.
