  • max dia for champion drums

    I have a 1950 champion to restore. The rear drums were badly rusted and pitted. I have turned them until they are true and clean, It took quite a bit. I cannot find anywhere in the service manual or stamped on the drum what the safe max dia is . Can anyone help?

      Take your drums and shoes to a Brake and Clutch shop and have brake lining made to fit the drums. It will make a world of difference in stopping. If you do be sure to keep the shoes matched to the drums mark them when you pick them up.

          Not sure about 50's drums, but later ones had a bevel around he circumference of the usable thickness. Once you turned the drum to the point where you couldn't see the bevel, it was out of spec.

          I hope you didn't turn it to get rid of the pitting. Just trueing them would be suitable.

              I think you are pushing your luck with the 9.096 one, that is 36 thousands over what they are supposed to be turned.When I was in the repair business we did not turn them beyon specs for liability reasons.It is your vehicle of course and you can do what you want to do. If you need drum I and other vendors can provide one.
