Hello, I am looking for Front and rear brake drum diameter and service limit. Any help will be appreciated.

Nominal is 11.00 x 2.50 on the front and 11.00 x 2.00 on the back. The service limit should be cast or stamped onto the face of the drum, typically near the edge, but the discard limit is 11.090"

Thank you Sir. I appreciate the quick reply. You seem to be very knowledgeable about these old rides. I appreciate you knowledge and willingness to share it.

There was no service limit stamped or cast on these brake drums.
I don't think that practice started until the late sixties.
However, you are correct that 11.090 is considered the maximum size for serviceable drums.
