dibarlaw Posted July 3, 2021 Share Posted July 3, 2021 (edited) My 1925 Master has a real badly warped rear drum. Any leads on a good drum? This one is about 3/16 out of round and very worn on the inside. Interchanges with many 40 series models from 1923-1928 Apparently, the previous owner drove the car quite a bit with only one wheel doing any braking. Using the E brake. I rebuilt the front brakes as most of the actuator assembly was frozen and broken internal return springs. REAR DRUM SPECS. O.D. 14" I.D. 13 5/8" Depth 2 1/2" Hub Bore 4 27/32" Bolt circle 6 3/4" According to the 1929 Master Parts Book.... Part #184606 is for... 1923-41-44-45 1924-41-44-45 1925-40-44-45 1926-40-44-45-47 1927-Series 120 1928-Series 120 and 128 Best regards: Larry DiBarry 717-263-3804 Edited July 10, 2021 by dibarlaw Added content (see edit history) Link to comment Share on other sites More sharing options...
dibarlaw Posted July 11, 2021 Author Share Posted July 11, 2021 Corrected depth to 2 1/2". Link to comment Share on other sites More sharing options...
nickelroadster Posted July 12, 2021 Share Posted July 12, 2021 I just realized I might have one of these. Let me pull the wheel down from a high shelf and measure it tomorrow. Link to comment Share on other sites More sharing options...
dibarlaw Posted July 12, 2021 Author Share Posted July 12, 2021 (edited) Thanks for checking for me. That would be great! Fred Rawlings is also working on one but it has to come off an chassis that had been left outside for many years.

nickelroadster Posted July 14, 2021 Share Posted July 14, 2021 dibarlaw, I am sorry. My brake drums are 12" in diameter. I thought that they came from a fairly big Buick but evidently not. Good luck with your search. Link to comment Share on other sites More sharing options...

dibarlaw Posted July 15, 2021 Author Share Posted July 15, 2021 I had gone to send it 8 hours earlier but forgot to hit submit reply.... Oops. I did check my 1925 STANDARD drums and for reference they are 12" I.D and 12 3/8" O.D. Thanks again: Larry Link to comment Share on other sites More sharing options...
nickelroadster Posted July 17, 2021 Share Posted July 17, 2021 Well now if you are talking 12" I can probably help you. Maybe the best thing to do is for you to get all the measurements again just to be on the safe side. Link to comment Share on other sites More sharing options...
dibarlaw Posted July 17, 2021 Author Share Posted July 17, 2021 (edited) Thanks again but I know the needed drum is.... REAR DRUM SPECS. O.D. 14" I.D. 13 5/8" Depth 2 1/2" Hub Bore 4 27/32" Bolt circle 6 3/4" Having the 1925 Standard Touring has helped in being aquainted with various parts and assemblies and comparing to the Master.. Unfortunately hardly anything interchanges between the two model series. At Hershey for example I could Identify 1920s Buick parts from 20 feet away but at less than 10 feet I may be able to tell if it is a Master or Standard by size.

dibarlaw Posted August 1, 2021 Author Share Posted August 1, 2021 Still looking... I have had several say they have what I need but no confirmation as yet. REAR DRUM SPECS.
