Brake drum on 62

[Terry D.]

Not at home so I need a little info, what is the standard inside diameter of a front and rear brake drum on a 61-62 Corvette? Also what is the point when you should replace due to wear?
Thanks

Correct. Nominal OE diameter is 11.0". Later service drums had the 11.090" max diameter stamped or embedded in the casting. This was a new FMVSS that went into effect, IIRC, on Jan. 1, 1968, and it also applied to minimum disk rotor thickness.
