I know how good it feels to find the cause of a problem. Glad you found a cause for yours. I say that because it is also possible that your front brakes may be contributing to the vibrations. That can be determined once you fix the rears and do the test again.

A couple people on this board have reported buying new drums that were out of round, neither of which bought Toyota or Brembo drums. It is also possible that your drums are fine but that the hubs are dirty or the rear wheel lugs were over-torqued when they were put back on. Sometimes the factory installed paper gasket that goes between the hub and the drum gets stuck to the hub the first time the drum is removed. If enough of the gasket is stuck to the hub when a drum (new or old) is installed, the drum can get cockeyed which results in rear brake vibration. Rust could also cause this problem.

A few people have had their rear drums turned and ended up having a worse problem. Can't recall anyone reporting that they had their drums turned and they got better. If you're certain your hubs were clean, you may need to take them back for an exchange or refund. You might want to try pulling them off and reinstalling them 90 degrees off to to see if that produces a change. You could try all 5 other postions as well, but that would take a bit of time and effort.

Were your hubs clean when you installed the new drums? Were the lugs torqued to 83 ft/lbs when the wheels were put back on?
