fixitman Posted November 27, 2021 Share #1 Posted November 27, 2021 I have (2) used aluminum brake drums. ID of each measure about 9". They were painted black long ago and do not look pretty any longer. Are these drums of any value to anyone? Thanks, Dave Link to comment Share on other sites More sharing options...

Thanks, Dave If they can be turned on a brake lathe, and still be in spec, they are serviceable. Otherwise they aren’t worth much at all. Link to comment Share on other sites More sharing options...
Patcon Posted November 27, 2021 Share #3 Posted November 27, 2021 (edited) I know they can be relined (it's expensive), but I thought someone was making new aluminum drums Found: https://whiteheadperformance.com/product/datsun-240z-260z-280z-oem-aluminum-rear-brake-drums-nos-2/ https://www.thezstore.com/page/TZS/PROD/24-5050A So I would say out of spec is scrap metal. If they can be turned, I would do that Edited November 27, 2021 by Patcon 1 Link to comment Share on other sites More sharing options...
fixitman Posted November 27, 2021 Author Share #4 Posted November 27, 2021 I believe the drums are still in spec. Would anyone be interested in buying them for a very reasonable price? Link to comment Share on other sites More sharing options...

( of whiteheadperformance) there is a steel drum in the alu drum/casing? (they will last even longer?) So they are a remake? Years ago i bought a set from someone that had a Datsun original set used on.. i believe the car brand was TVR? He had only drilled the 4 boltholes a bit bigger and they fitted.. (I only have to fill it with some small rings to use it on a 240z again..)

Patcon Posted November 30, 2021 Share #8 Posted November 30, 2021 To my knowledge, all the aluminum drums have a steel liner. 1 1 1 Link to comment Share on other sites More sharing options...
26th-Z Posted November 30, 2021 Share #9 Posted November 30, 2021 Yes, steel liner. You wouldn't expect the brake pad to rub on aluminum. 1 Link to comment Share on other sites More sharing options...
dutchzcarguy Posted December 1, 2021 Share #10 Posted December 1, 2021 Yeah.. hadn't really thought about it.. btw How do they renew them? On a lathe and get all the steel out and put in a new steel liner? I can imagine they take most out, and weld the new one in on the edge and clean the edge by putting it in a lathe and make a nice edge? Heatshrinking could be a bit dangerous i think.. because these things can get very hot and the steel could come out the aluminium casing? Maybe a bit of both?

madkaw Posted December 1, 2021 Share #11 Posted December 1, 2021 I think the relining process is about 250$ per drum . Probably end up better than OEM . Not many that do our drums . Cast iron drums are much heavier , so this a decent option . I have extra drums laying around that are in spec . 2 Link to comment Share on other sites More sharing options...
Patcon Posted December 1, 2021 Share #12 Posted December 1, 2021 Yes, I would think they would lathe them out completely or just partial and then install an interference fit liner. I don't know if they tack them or not 1 Link to comment Share on other sites More sharing options...
