An easier solution would be to install a non-boosted dual master cylinder. Pedal and linkage parts from a non-power brake Packard are available. Mounting the master cylinder will require some thought and work, but doable. I had the Easamatic power brake system removed from my 1955 Super Clipper (no torsion level and similar to your 1953 Patrician) and replaced with a conventional single cylinder master cylinder. All parts were from an earlier Packard. The brakes worked remarkably well, they were well modulated and easy pedal action. Ross Miller did the conversion. This should be a more than satisfactory change even with disc brakes on the front. Of course, you will need a proportioning valve so as to have good brake balance between the front and rear brakes.
