When the pads are getting close to replacement as given in your statement then the heads of the rivets are within 1/32" from the lining surface (service manual, section IV "brakes"). In this case a satisfactory adjustment cannot be obtained and the degree of wear should have an influence on the pedal free play and the fluid level in the master cylinder reservoir. No need to wait until metal-to-metal contact.
Gerd, I think you missed my point. 1) There is no ongoing adjustment of disc brakes as they are self-adjusting. 2) The master cylinder reservoir reduction in level will be unnoticed at the pedal if there is no leak. One could actually "pop the top" and visually inspects the level, but most owners do not. 3) Some owners, for which brakes are designed, are oblivious to anything short of complete and catastrophic failure.
Bottom line: I was just trying to point out another reason why disc brakes are better than drum brakes. But, as I have posted before, for Packards that do not drive in the aggressive traffic of modern cities -- or the Autobahn in Germany -- disc brakes are probably not needed. I have disc front brakes on my 55 Pat because of having to drive in Las Vegas.
I have also driven on the Autobahn in a BMW...now that was fun!
