I have a 97 2500 auto. i replaced the p/s pump a few weeks ago and the steering gear just yesterday. Steering is very smooth now and everything was good until today, i was on my way to work and BOOM there goes the brakes. i check the p/s fluid level and inspected it and the brake lines. Everything looks good other than a small leak around the p/s pump that i cant find the source. Hydroboost problem? What could be causing this?

If it was a hydro-boost problem the pedal would be very hard to push.
What exactly are your symptoms?

well the pedal goes almost all the way to the floor, and i got about 5% of my brakes. I was goin to work and they just went out no warning or anything. Thats the only thing thats really going on with it is that the pedal goes almost to the floor and 95% or braking is gone.

one ofmy brake lines rusted and burst on me last winter and i had very weak brakes right away

Look at the brake fuid level in the master cylinder. If its very low then chances are something in the system exploded dumping all your fluid. I assume the "Brake" warning light is on all the time? Check for brake fluid leakage on the wheeel cylinders, calipers and all hard/rubber lines, if you find a big mess of brake fluid there is where your leak is. Bad seals in the master cylinder would make your pedal crep to the floor, but you should still have breaking action by pumping the pedal.
