TR2/3/3A Alfin 10" Brake Drums

[Redoakboo]

I have a 1957 TR-3 with Alfin brake drums on the rear, 10" dia. There are worn way past any additional turning. Does anyone know a source for these drums?

I have no idea if they are still available but have an alloy drum from the Datsun 240z on my TR4a. These do not have the radial fins but have fins across the width of the drum, about 1.5 inches long, so may provide a cooling benefit in addition to reducing unsprung weight, but obviously do not look the same.
I would try sources in England for Alfin, possibly someone still makes them for the vintage racers.

Well, I did come across this relative to the Porsche 356. I'd assume that, if anything could be done with yours, it wouldn't be cheap, but perhaps it is at least possible?

ISTR TRF was selling these, slightly modified 240Z drums, but i couldn't find them on their website. Perhaps give them a call?

He wants 10" drums, TRF supplied 9" finned same as 240Z. 10" will be tough to find.

Alfin 10 inch are extremely scarce. There was a set on eBay quite some time ago that went for BIG bucks. Probably CID got 'em. I'd take Andy's advice and check into re-lining yours. Several shops seem to be doing them and several racers race with them.
I think the 9 inch Z drums will fit also if you use the Triumph 9 inch shoes and backing plates, but there goes originality (I think those Z drums are the tooth type too).
If you are not racing, I don't think there is much if any performance advantage to the alfin drums on the rear, bu they do look very cool behind the wires.

Moss Europe has regularly listed them, but shows them now to be not currently in stock: https://www.moss-europe.co.uk/shop-...ke-system/rear-brakes/rear-brakes-b11577.html

Kinda pricey, but not really compared to modern parts or bespoke spares for other cars.

Here's another place that says they can reline TR Alfin drums https://www.jgrelining.com/
