Re: 1940 120? Front brake drum, 12"

tsherry,

On 12" diameter, the depth can be 2-1/4 (for 2"shoes) or 2-1/2 (for 2-1/4 width shoes). Measure the diameter accurately. I think there's only 1/10" of wear allowed. If that much or more, a shop may not mount it, legally.

If the diameter is 12" to 12.05", a buyer ought to know. "Looks in good condition" doesn't mean it was measured and is usable. If it doesn't measure out, return it for your guaranteed eBay refund.

And please, if someone knows the accurate amount of wear for a 12" drum, chime in here.
