You might find some food for thought in this thread. I'm not looking to start another long discussion about drum versus disc brakes, that's been aired more than adequately. But if you're interested in keeping your 55/56 original and aren't satisfied with the brakes (my own opinion is that they can be and often are pretty marginal), perhaps you'll get some thoughts here.

good information!
I can tell you though that you can't just drive these cars like mordern cars. i know when i drove my dad's 1970 Dodge Dart Swinger with manual brakes....it had to be way more careful of distances, etc.. so i expect to act the same in my Packard personally. i mean i don't expect it to be anywhere near what my 14" 4 piston upgraded brakes on my BMW Z3 are capable of, so i would drive it accordingly. i know everyone knows this, i just felt like saying it i guess. carry on ;0) Hank Attach file:  (87.97 KB) (59.53 KB) (75.19 KB)

Hank, great car, it looks like one of the first 6 cylinders, unfortunately too small for my bel... for my belt.
 Quote: ...you can't just drive these cars like mordern cars... I think it depends on the basis of comparison. Hank's Z3 probably stops faster than one or another vehicle I had the doubtful joy to ride with. The pic shows a farm tractor without power steering and power brakes, no brakes at the front axle, weak rear drum brake and crash box (not synchronized gear box) but 24 tons towing capacity. Successful built 20 years after the downfall of Packard and exported in several countries. I don't say that it needs a tractor to make a Packard appear modern but high deceleration due to braking isn't an invention of modern times. Attach file: (13.52 KB)

(URL not included) Dave, sorry for the thread drift (in opposition to your above statement), but the main thing I took from that writeup is that drum brakes are a PITA to set up and maintain, compared to disc brakes. One of many things NOT available on drum brakes is the "telltale" in the disc brake pads that warn a semi-alert driver to the fact that the pads are getting close to replacement by "squeaking". No such thing in drum brakes until there is metal-to-metal contact by which time the drum is probably toast. Craig

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 - so much so more if the talk is of glued lining.

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! Craig

Craig, like you I was talking about drum brakes.
Bottom line: the German Autobahn statistically are the savest roads in my country.

Craig, I'm not sure to understand but if you mean how much it is I think it is around EUR 2,500 to get a driver's license. You have to go through a theoretical instruction including test and driving lessons including test. The quantity of driving lessons depends on your skills. Both test are in the presence of your teacher and an external examiner. It isn't easy to get the license, many new driver's need more than one attempt - an expensive affair!
And to stick with the initial issue I would like to add that the pedal free play has been an important issue in the driving school of the 1950s.
