Such a complicated system, where to start?

Is your Bijur chassis lubricator functioning? Among the many points on he brake system that require lubrication are the ends of the pedal cross shaft, the ends of which are lubricated by the Bijur. Another of many places place where excessive friction can develop within the cable assemblies, strip the inner from the conduit and use a graphited grease. More obvious things to check are within the drum, shoe return springs, cams and levers, etc.

It's an extremely potent brake system, and complex. I'd recommend starting at the individual wheels and carefully working your way all the way back to the pedal. And don't ignore the parking brake, it actuates on all 4 wheels and many of the component parts are used in common with the foot brake.

Initially you could disconnect the cable from the booster cylinder to determine if your problem is there. And yes, of course the booster cylinder does have a lubrication need, assuming its in good working order, you might add perhaps a half ounce of vacuum oil.
