68 Barracuda power drum brakes,peddle hard.

I have a newly aquired 68 Barracuda fastback with 318,A/C, p.steering and power drum brakes.Everything is new on the brakes.Drums,shoes,hoses.I noticed when stopping the car it seems like there,s no power?It,s been years since I,ve driven a car with power drum brakes,but these don,t seem like power brakes to me.Maybe I need to do a 4 wheel bleed of the system,but can,t see why this wasn,t done when the new parts where installed.Is it just me or is it normal for these to feel hard?My 66 Dart with manual disc stops way better.

Oh and the booster is fine,holds air fine.

Any input will be appreaciated.Thanks
