Anyone have any idea what brake drums have the studs attached ? The car was built in the 80's, and I don't know what the trend was back then. I want to check the wheel cylinders and shoes, but when I removed the wheel and tire, the brake drum has the studs attached, and doesn't just lift off and the studs behind. There is a screw in dust cap that looks like it could be holding the drum on, but I wanted to get some input before I jump in with both feet.

thanks, mike
