Brake Drums
Lots of cast parts are being made in India now. Their castings are decent but the machine work is usually crap. They make cylinders for antique Indian motorcycles and they are pretty much junk.
That being said, I have some rock auto 11" drums I just bought and they look to be very good quality. Im sure the metal is much softer and they wont last as long.
Im just glad that these are still available new.
