My gut reaction was a failing accumulator sphere. To check, turn key to position II (without starting) and allow the pump to run until the ABS and Brake lights are extinguished. With ignition still on, pump the pedal two times and the pump will again recharge the sphere. Then turn the car off, and you should have a good 25-30 pumps of the pedal before it goes hard. If it goes hard right away - bingo; Very likely a sphere not holding pressure.
If the Brake and Anti-Lock lights do not go out and the brake pressure is always hard the electric pump may be not operating. Check to see if the booster motor is operating and check the fuse feeding it to see if it is blown.

I just wanted to say that replacing the accumulator had fix the problem, I bought the part used online, I actually replaced the whole thing, not just the ball but the accumulator itself. easy, took 5 minutes.
I now would like to get the A/C to work, I'll start a seperate thread.
