So, a few weeks ago I had my drums resurfaced because the shoes had worn pretty deeply into the sleeves (these drums are aluminum with steel or iron sleeves). After getting them back I noticed I still had brake pulsing and figured it was due to my front rotors being slightly warped rather than the rear drums, but turns out it's my drums. I haven't yet decided what to do.
With the drums attached I've found that the brakes will rub only at certain spots on the drum when adjusted to where they barely start to rub, which tells me they're warped. My guess is that the shop removed material from the drums to resurface them, but that they didn't remove it hub-centrically. Or, maybe they warped again, because they're not as thick anymore. I imagine it's a lot easier to warp an aluminum drum than a steel one.
So I'm thinking rather than spend more good money on fixing old drums which have already had material removed, I might just replace them.
G1Parts has OEM drums available for $85 each. They weight 4lbs 10oz.
These look to be steel. Weight isn't given.

The image on these probably doesn't represent the actual product (shows 5 lug), so unknown:

These appear to be mostly steel, but with the aluminum cooling fins from the originals attached to the outside:

RockAuto has the Centrics listed above for $23 (each), which seems fair. However I believe the all-steel Centric drums weigh in around 9lbs, or roughly twice as heavy as the OEM drums. Unsure if I should just live with out-of-round drums, spring for new OEM drums, or try again with resurfacing and make the ones I have even thinner.
