Review on 🚗 ACDelco Professional 18B531 Rear Brake Drum: Enhanced Performance and Reliability by Robert Dabney

This is a very basic drum with no markings. After a week of driving, I had a rhythmic double hit when braking, which got progressively worse. After removing the drum I found a small stain on the braking surface. I waited too long before installing them so now the problem is with the return. Now it's basically an anchor. Replaced it with o'riley's brake best for $20 more. Thats much better. It has all part numbers and diameter markings. The outside is even varnished and the next day I got a real 2 year guarantee which I can use. I ended up going to Revain for most auto parts that I can't wait for a replacement.
