Re: 1955 Packard- weak brakes

All the brake hose have been replaced this year and the wheel cylinders were replaced in the last couple years-and the system is not leaking fluid. I've bled the brakes and with the engine shut off the pedal is nice and hard just the way I like it, but the minute I fire the old girl up the pedal sinks to the floor.
