Have a full brake pedal when engine is off but goes to floor when running?

Not enough brake fluid is the most common cause of a brake pedal that goes all the way to the floor when the engine is running. To stop a running vehicle, enough braking force should be delivered to the braking pads on the wheels. The brake fluid helps to maintain the required braking pressure.

What can cause a brake pedal to feel soft and travel to the floor when pressing it?

Air in the brake line(s) is the most common cause of a soft/spongy brake pedal.
