Usually if you have a hard-pedal feel, it's either the booster took a dump, or you have a vacuum issue. Since the brakes are power-assist, the booster needs a decent amount of vacuum in order to have a nice pedal feel. The line from the back of the intake manifold to the booster also houses a one-way check valve, last time I checked, that is integrated inside the hose itself - years and years can wear these down, and if they go, it allows boost pressure into the booster and kills the booster. I would start with a vacuum-check (what's your vacuum/boost guage reading at idle). If vacuum is ok, replace the booster and test the hose to the booster to make sure the check-valve is working and not allowing boost pressure into the booster or you'll end up needing a new booster shortly after replacing it.
