I had some serious problems taking off my drums (as u can see from my other post)... i did get it off but there is a groove in it now from the shoes rubbing the inner walls of the drum?! Is this normal?

So now if u ran ur finger from the inside out on the contact area of the drum to the shoe, there's a groove where the shoes make contact with the drum.

Time to change drums? Can drums be resurfaced? Jus wondering...

 

Drums can be resurfaced just like disks. There's a max diameter, just like there's a min thickness for disks. So the shop is supposed to look it up for your car & they aren't supposed to do it if they go over the max diameter. Maybe it's cast into the drums where you can read it?
