My brakes are hard I will not come to a complete stop

Sounds like a bad brake booster. If you are getting an extended braking distance, you may also want to check for a rear wheel cylinder leak. You also might want to check to see if the engine vacuum is low. Your vehicle should have a sensor that determines if the rear wheels are braking. If hydraulic pressure is uneven between front and rear you will usually see a brake indicator light come on. Also make certain that you are getting enough vacuum to the brakes. Low vacuum can be caused by a number of problems. I recommend using a vacuum gauge for this diagnosis.
