Where does the fluid in the brake pads come from?
Your brakes are a hydraulic system, which means that fluid makes them work. Pressing the brake pedal shoves brake fluid out to the brakes at the four corners of your car. In a disc brake, fluid pushing into the brake caliper is what moves your brake pads inward to clamp down on the rotor and slow the car using that friction.
What happens if the brake booster is bad?
The booster is a mechanism that uses vacuum pressure to take the force being applied to the brake pedal and amplify it.

The pedal will go all the way to the floor and the car will be harder to stop.
