47 front brakes

I have a stuck front brake drum, I'm pretty sure the brakes need backed off, I have tried the two 11/16 adjustment bolts that have the spring under them, I can get about a turn out of them and then it gets pretty solid feeling. Any suggestions would be welcomed.
 
the two 11/16 bolts have a cam on the inside. turning them out, towards the tire, they will stop when the shoes are tight to the drum. turning them in, towards the axle, takes the shoe off the drums to loosen. the cam has a notch at the end of its travel so it will stop at the innermost point. turn them in, then get a little violent with a rubber hammer on the backing plate, perhaps rattle the shoe off the drum

Back to the garage.:)
 
How big of a chore is it to get the old hub onto a new drum, is that best done by a machine shop, the drums need turned but they look a little lite, I haven't taken them in yet but I don't have high hopes for them. The car still had good pads, just worn into the ruts, lol. Is Macs the best bet for drums, the four at a time deal kind of sucks.
 
Replacing the drums on the hubs is a job for someone that knows what they are doing and has a 20 ton press. Contact a local Model A or early V8 Ford Club and see who the members use. Don't leave them at a shop that thinks they can do it but hasn't done it before. Sorry I don't have any recommendations as the best place to buy drums.

The studs are actually rivets that have been deformed to lock the drum to the hub. A press will likely deform somethng. The studs are also pretty soft. I use a 5/8 deep hole saw and run it in to cut the pushed out metal swedge. This does not hurt anything. It goes supprisingly fast.

andy is right, dont try to press them out without cutting with a hole saw. you will warp the hub. dont ask how in know this

Why do they say that these drums can only be used with 1940-41 hubs?

The early drums have the hub on the inside and the later ones have the hub on the outside. You can't mix them. They interchange on the 1940-48 vehicles as a hub/drum assembly without problems.

I'm aware of the differences, but why does the source referenced above state that they are only for use on the early (40-41) style (with modifications)? They are also out of stock on that site it appears.
 
the new drums from mt products are only for the "drum over the hub" style. no one that i am aware of makes drums for the later 46 48 "drum under"
 
good point randy!! you would think with 47 in the title i would not have gotten off track. confused with the other drum thread going now maybe? or just crs. lol
