Unfortunately there are several possibilities. First off I'd check brake pad and / or shoe thickness. Worn pads / shoes can cause this as the caliper pistons have to move to the nearly full extent of safe travel. I've had cars where the person only brought the car in after the pad was gone, the vented rotor was worn through on the caliper piston side, and the caliper piston fell out of the caliper. This car was a safety hazard LONG before they lost brakes completely. A failing master cylinder or old brake fluid can cause this (brake fluid absorbs moisture and breaks down which lowers the boiling point and causes brake fade. It could be as simple as a self adjuster on drum brakes frozen up or on models that use the emergency brakes to actuate the self adjuster present problems for those that never use their emergency brake. Please note that sometimes the emergency brake cable will seize up when not used for a while so a brake inspection by a qualified person may be your best bet.

What brake pedal is the cause of air being in the brake system?
The brake pedal has nothing to do with it. If air is in the system then bleed the brakes.
Can the brake booster cause your brake pedal to go to the floor?
No, a busted brake booster will not cause the brake pedal to go to the floor. It will however cause the brake pedal to be extremely hard to push. A defective master cylinder will cause what you describe. Replace the master cylinder and bleed the brakes. It can because it happened to me. The booster lost vaccum and the pedal went to the floor. Sorry, you are wrong. The only reason the pedal went to the floor was because the master cylinder failed. The brake booster only boosts the pressure on the master cylinder and allows you to not have to push so hard on the brake pedal. Cars of yesteryear did not even have a brake booster and they stopped just fine albeit you had to push the pedal allot harder than with power brakes. A failing brake booster will not cause your pedal to go to the floor although it might cause it to go lower than normal before the brakes apply. As long as the master cylinder is good you will still have brakes, but you will have to really push hard and might even have to pump them up in order for them to stop the car.

Hardness in the brake pedal can because by low brake fluid. Air in the brake lines can also cause the pedal to push hard.
