Greetings: I'm working on a customer's 1930 Eight. The brake pedal goes almost to the floor. I've adjusted all the linkages and followed all the Packard factory directions and it still goes to the floor...with just enough room left to provide SOME braking action. The linings (3 shoe) were redone only a few miles ago (former museum car) and are 3/16" thick. I can get the secondary and auxiliary shoes to activate normally, but there's a lining/drum gap on the primary that's significant. That's what allows the pedal to go so far. I've seen some cars where one lining was thicker than the other. Is this one of those cases? Should the primary have 1/4" thick lining. Thanks in advance.
Correct lining thickness for all shoes is 3/16". You've got an adjustment problem as even when the shoes are half of more worn there should still be enough adjustment to get a normal pedal.
