I just went through an ordeal in which i took my 2002 Honda Civic to a chain shop (big mistake) and had to go back numerous times due to an issue which was apparently related to the new drums being “out-of-round”. The mechanic has now resurfaced them twice. Now I’m reading a bit more on the internet…

New drums out-of-round - resurface or replace

Brake drums go out-of-round from shipping/storing then on edge instead of flat. It even says on the box for a brake drum, “DO NOT STORE ON EDGE”. That’s the reason.
