Model T Ford Forum: Forum 2013: How common of a problem is this?

A few weeks ago I removed the engine from the coupe to replace the badly pitted low drum. I found the brake drum has a crack in at least 3 of the bolt holes. It's a shame because outside of this the drum is very nice. How common of a problem is this?

Thanks,
Stephen

Very,and especially if it is a 26-27.

How far do these bolt hole cracks usually go? Has anyone seen a failure where a bolt hole splits completely in a 26/27 brake drum?

I was thinking it might be feasible to use such a drum in a car with outside brakes where the brake drum doesn't get much heat stress anymore..?

Never seen one that completely broke out, could happen I guess.

Jack is correct, it very common on 26/27 drums and I would bet most of the ones running have a few cracks in this area. But when you find a cracked drum I would like to find a better one, good ones are becoming hard to find.

I think the drum is under stress on acceleration and braking. More if a panic stop? The drive plate is bolted to the drum and that what makes the wheels go round.

Missed us here in Tulsa, I know the storms that hit OkCity got to some of the T group there but haven't heard of damage other then some roofs blown away.
