Brake peddle hard but goes down slowly?
Air in a brake line or a bad master cylinder could cause this. Bleed the brake lines if you have been working on any brake cylinder. If this happened without any warning, the master brake cylinder is probably the cause and should be replaced.
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.

Sounds like you may have moisture in the brake fluid. Have your brake fluid totally replaced. Your master cylinder may also be failing. Hold steady pressure on the brake pedal. If it very slowly goes down replace the master cylinder.

The master cylinder on a 1999 suburban is pretty easy to change.
