Guys, I'm trying to get the front brake drums of my 69 GTO. I've backed of the adjusters but they are still firm. The rears came off as easy as.
My question is though, there are two types of wheel studs on these front drums. Some seem to be attached to the drum. "I could be wrong" but please have a look at the photo's attached. Maybe these need to be unscrewed?
The front drums are an assembly to include the hub - unlike the rear brakes where you can remove the drum. So you typically pull the entire assembly.
The one stud looks like it has the factory lock ring on it. It is a thin metal piece which I usually just bust it off with a hammer and chisel or even a small screw driver. One of the studs may have been changed - which is done with the drum assembly off.
You may get lucky enough just to remove the drum, but you will have to get that factory lock ring broken off. Then you might be able to beat it from behind with the BFH, but you risk breaking the drum. I always pull the assembly, and then knock the hub through the drum. While at it, you can install new inner and outer bearings/races & seal. But, if the drums are good, they can be turned. If they are too worn, then they will need to be replaced.
You can also inspect the brakes with the assembly off and install new brake shoes if needed and a small parts kit.
Of course, converting to a front disc brake set-up is the way to go unless you have to keep the car original. If sticking with drums, don't use the lifetime type brake shoes as they are usually a hard material and won't stop very well. I always get the lower end/inexpensive shoes as they are a little softer and grab better.
Found this YouTube video that shows pulling the drum while leaving the hub. You will see it is a pain to do it this way, so I just assume pull the assembly. You might want to give this a shot first:
