Aluminum brake drums ?
« on: January 11, 2019, 03:23:17 AM »
I'm rebuilding the rear drum brakes (78 TA) and all hardware, thinking of installing aluminum drums.
I see the Cardone brand on ebay at 101.35 each. Has anyone used aluminum drums with success?

I’ve got them on my 77TA.  They look nice and don’t rust like the iron drums.  Not really sure about any significant upgrade in performance during normal street driving though.

apart from the slight weight differences, and maybe the rusty brake dust, you wouldn't notice anything unless driving in such a way that the drums are hot anyway where heat is dispersed a little better. I'm not sure how they would compare on the street, if notice a thing.

Actually, those I've seen actually have a steel inner ring, so brake dust would be the same. I painted my cast iron drums, with cast iron heat paint, so visible rust wouldn't be an issue.

Agreed.  The question I was trying to answer when deciding on this purchase was if you get more for your money by adding rear discs instead of the aluminum drums.

Hard to say since even adding rear discs is barely worth the money over drums.

the housings and visible part of the drum is aluminum, the braking surface is still steel.

you get 3 things:

1. less weight
2. a visibly better appearance because the aluminum wont rust.
3. better cooling but its the rear brakes so how hot do they really get?

I think the biggest thing is you wont see a rustry drum behind the wheel.
