Brake Drum question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I know, I know, you're still waiting to hear about the "klunking" issue, but wanted to ask about the "pulsing" brake drum issue mentioned in it (Wife says I have "AAADD" - Advanced Age Attention Deficit Disorder); Anyhow, was thinking of replacing the drum, since it looks like it would cost about the same as having someone turn it (O'reilly's has it for ~$25).

Question is: If the brakes themselves look ok, should I just get the new drum or should I do more?

I would at least make sure the adjuster is working good. Depending on how worn the drum is that you are replaceing you may have to back off on the adjustment to get the new drum on.

if you have original drumps, and they can be turned, then turn them. The replacements are junk.

Do Auto parts stores even turn them? It's been so long since I've had a truck this old, that I don't remember whether they can do it or not?

Turn the old drum! It's old seasoned iron & shouldnt warp like a new one (probally made in china...) probally will. I buy new ones as a last resort.

Yes, you can have the old ones turned... make sure they don't turn them too far though, there's not a whole lot of room for going too far on these.
The replacements are pretty lame. No hole to adjust the shoes through, no lip to hook the spring to, and worst of all, they warp like a mo-fo.

The tricky part is doing it while the wife isn't looking-she's pretty fed up with any more "repairs" to the truck....

Mebbe I'll buy an el cheapo, pull the old one off, have it turned and then put it back on =]

if you get new ones, plan on replacing them at every brake job, that adds $25 a wheel at a minimum.
If you have old ones, have them measured, if they are thick enough, then they are thick enough.
