You said the pedal was "rock hard after one pump" so I imagine the master cylinder is bad. It should be rock hard with NO pumps which is how you normally brake.....just push the pedal and after 1/2 inch or so the pads should hit the rotors soooooo that is not happening.

If it were me I would put some saran wrap under the reservoir cap to keep all the fluid from draining and then pull the master cylinder off the car. You can pop the boot off then remove the snap ring which is usually how the internals are held in. Let the fluid drain out then pull the internals to see what is wrong. There are diagrams on the net (not sure if any are here) so you can see what is supposed to be there and how it goes together. Good luck!
