i was changing the shoes on my truck and noticed far inside the drum is a pretty nice little groove carved in it and i was just wondering if i need new drums or will it be ok i dont need much stopping power. the groove is very small but a little deep should i be ok? i never stomp on my brakes im pretty easy on them.
If there is a groove in the surface that the shoes touch, I would turn/replace the drums. Are you going to be okay for a while, maybe yes, maybe no. You can't plan for panic stops caused by the other guy.
Have to look again, I don't remember seeing anything like that. I did have to replace D/S drum and wheel cylinder when I bought the truck. But that was 4+ years and thousands of cars ago.
Seems to me I was told it is a federal law. At the last shop I worked at and one years previous we had a complete brake setup------ brake drum lathe, shoe arching machine, and rivet remover and rivet press for everything from air brake drums/shoes down to pickups. Everything always had the max drum I.D. stamped on the drums. With that said, other than air brakes (no bleeding, etc), I always hated doing brake jobs.
