When to replace brake drums? (Silverado)

Not necessary if nothing is wobbling badly. Get them refaced.

Probably didn't need new rotors (old ones can be turned at a garage).

There will be a core charge for your old drum shoes.

ETA: Only work on 1 side at a time so the other can be your guide on reassembly.

When I was working at Salisbury Dodge we got a Durango traded in that had front rotors that looked like that. The previous owner had put power steering fluid in the brake master cylinder and seized everything up. It was the most expensive brake job I ever performed. New rotors, drums, rebuilt all calipers and wheel cylinders, flush all lines, replace HCU for the ABS, etc.

Seems like nobody's cutting anymore.

Liability, cost, etc.

In reply to everyone who suggests turning rotors and drums, it's more of a pain in the arse because I have to get someone to drive me while my truck sits on jack stands while they turn them. Plus, with the labor charge, it costs about the same amount as me just buying new rotors. The drums may be slightly more expensive but the convenience of having everything ready to go right then and there is worth an extra $10-$15 for me.

But if the consensus is either to rework them or have them resurfaced, I'll probably just change the shoes. They won't be taking most of the brake force as the fronts will be. And I'll be changing out those rotors for brand new ones.

Thanks for the advice dudes.
