Usually, the pedal going to the floor indicates that there is no [or very little] brake fluid in the system. That of course is not the cause, as you must find where and why such a massive amount of fluid leaked out.
You can try refilling the brake Master Cylinder fluid Reservoir with the PROPER type of brake fluid and see if that solves the problem, but I doubt it. After filling the Reservoir, you will have to PROPERLY "bleed" all air from the entire brake system. For a novice, this can be a difficult and daunting exercise. You need to get a service manual for your year, make, and model vehicle [these are available at your dealer, and at most if not all of your local auto parts stores (like Autozone, O'Reilly, etc.)].
The instructions and recommendations for refilling the brake fluid, bleeding the system of air, and then checking the brake system for sources of leaking will be in that service manual. I recommend that you very carefully read, reread, and learn the process BEFORE you try to refill and bleed the system.
IF there is a leak, or leaks, in the system, the replaced fluid will also leak out, so it will be necessary to find and repair all leaks to return the system to full service and safety.
If the parking brake pedal on your 2001 Dodge Ram 1500 is stuck to the floor, you might have broken the parking brake cable. Remove the rear tires to see if the cable is still attached and replace it as needed.

Have a helper pump the brake pedal on the 2001 Jetta several times then hold it down. With the pedal down, loosen the bleeder valve at a wheel cylinder and let some fluid flow til the pedal goes to the floor. Close the valve and repeat until the fluid does not have any air coming out with it. Do the same thing at the three other wheels.
This is usually cause by a stuck brake light switch on the brake pedal. Replace it.
Depress the brake pedal to shift.
Low brake pressure is caused by many things. Could be a bad brake booster, a leak in one of the flex lines, bad caliper, bad rear brake cylinder. Does the pedal go to the floor or does it just get hard as a rock and very little braking action without standing on the pedal?
If the brake lights stay on that probably means the switch on the brake pedal that activates them is defective.
