1994 Lexus ES300 Question: what is the brake booster

Answer 1
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 -
Comment 2
Not that I can think of. Plug the vacuum line going to it and see if it makes a difference. -
