Try bleeding your brakes. If there is air in the system it can give a spongy feeling to your brake pedal and require you to pump your brakes and/or put your brake pedal to the floor.

Brake pedal will slowy go down to the floor and leaks?

Leaks from where? If it's leaking around the pedal, you have a bad mastercylinder. If it's leaking at all, you have to fix that, then bleed the whole system. Not a major thing but I wouldn't drive it like that. if it fails completely, you won't have any brakes.

Defective master cylinder, low of fluid, or leak somewhere else in the system.

Is the emergency brake a hydraulic system that is automatically actuated when the driver depresses the brake pedal?

No, the regular brake system is a hydraulic system that is actuated when the driver depresses the brake pedal. The emergency brake is a direct mechanical system that is manually actuated when the driver pulls the hand lever or depresses the emergency brake pedal, which is separate from the brake pedal.

Why is vehicle brake bled?

they are bled to remove air out of your brake system. bleeding prevents you from having mushy brakes or your pedal going to the floor. it also makes the pedal tight and more sensitive to your feet.
