Hard brakes go to bad vacuum system or bad diaphragm in the booster. With the motor running pull off the soft line to the booster and see if there is a good suction sound. Then put your thumb over it and see if it has good neg. pressure. if it does then go to the booster. If it doesn't go backward from the booster line to the vacuum block on the fire wall and pull the large line that goes to the vacuum pump on the front of the motor do the same test as above.
