Your brake fluid is how the brake system converts mechanical force of your foot on the brake pedal, into hydraulic force that applies your brakes. Without fluid, your hydraulic brakes will not function.
It looks like a hydraulic clamp. When hydraulic pressure is applied with the brake pedal, the caliper clamps the disc brake pads to the disc brake rotor to stop rotation.
First production motorcycle with a hydraulic disk brake would be the Honda CB 750 in 1969
before you do anything, check you hydraulic mineral oil. its the #1 problem on these vehicles, Fill it up if empty and go from there.
Newer cars have a Power Brake Booster (or Power Disc Brake system). This system adds hydraulic pressure to the brake system, so when you push the brake pedal, it increases the pressure on the brake pads with hydraulic power. When the car is off, you loose the additional power provided by this hydraulic system. The brakes still work, you just need to push harder. Typically after the engine cuts off, the first time you press the brake it is somewhat normal (hydraulic pressure still in the system) but after that, the pedal becomes harder to press. It is the same concept with Power Steering - you have hydraulic assistance with the engine on, but none with it off (turn the key on without the engine on and turn the wheel - it is possible, just hard).
