If your brake peddle goes to the floor, you have lost brake fluid from your master cylinder in the engine compartment. Check your rubber brake hoses at each of your wheels, look for any signs of leaking brake fluid at your wheels, connections,lines, and master cylinder.

How does a clutch break work?

If a truck has a clutch brake it would only be used when coming to a complete stop. By pushing the clutch peddle completely to the floor you would apply the clutch brake. This stops the clutch disc from spinning making it easier to shift into 1st or reverse gear. Normal shifting while driving you would not need to or want to push the clutch peddle to the floor to activate the clutch brake.

Your truck makes a hissing sound when your brakes are engaged and your brake peddle travels all the way to the floor before stopping the truck also stalls when brakes are engages?

This one is easy. Brake booster diaphragm is ruptured, causing a massive vacuum leak, which will cause the engine to run poorly when the brakes are applied. A loss vacuum assist will make it difficult to stop the vehicle.
