I know, there are no stupid questions, just stupid people. So here I go. My 46 Ford coupe has these odd drums on the rear. They are shot and can not be turned out any further. I would like to keep my hubs and order a set of drums and studs from macs, joes, c&g, summit... whoever. My question: The hub either mounts to the front of the drum, or it is pressed in from the back (which i assume is like "normal") and simply has an additional component in the form of that plate.. If yall could take a look at these drums and verify that the hubs do in fact press in from the back (inside).....or the front. I also have a 47 and the drums hubs look quite different (i.e normal). The hub on the 47s rear brake is pressed in from the back (inside) of rhe drum. I am aware of the entire swedge cutting tool...hydraulic press process from start to finish. I have a machine shop for all that. I am just lining everything up and want to have all the right parts (new drums) in hand before I go up there.

No expert, but I believe that there are two styles of drums and hubs. Here's a bump for the smarter people. -Dave
The early style is like a modern brake hub with the hub flange on the inside of the drum. The later style as shown has the flange on the outside. The repo drums are all cast iron and don't like to have serrated studs pressed in. I think the only style drums offered is for the early hubs. I am often wrong. You need the early hubs. The easy way to cut the old studs out is with a 5/8" deep hole saw. It easily cuts the swedges.
Looks like i need a 51A-1125 or (51A-1105) hub with a 4" center hole to accept my hub from the outside Sent from my SAMSUNG-SM-G891A using The H.A.M.B. mobile app
You really should not post acting sure of yourself if you have no knowledge of what you are talking about. The hubs are different and the drums are different and can not be mixed. Please take a little care about what you post
@Andy If I was given bad information in the past, I'll submit to your knowledge. But I was told long ago, that the pictured (late) hub can be used for either style drum as it has the flange on the face side for the earlier drum and the narrower snout on the backside for the later drum. In other words, you can use the early or late drum on a late hub but if you have the early hubs, you are limited to early drums.
Contact MT Car Products and ask your question. Fordbarn folks can also help.Their high quality brake drums fit the OEM hub and studs. So, if you can remove just the drum you could use MT drums They also sell new hubs with studs. Use you OEM bearings. MT drums make it nice because you never again need a wheel puller to remove rear brake drums. http://www.mtcarproducts.com/Brakes.html 1st photo: MT replacement drum 2nd photo: MT hub comes with studs installed 3rd photo: MT hub with new seals installed 4th photo: Backside of OEM Ford early rear drum 5th photo: Front of OEM early ford drum
The hub flanges are spaced differently so the brakes surfaces stay in the same position. The late hubs do not have register to position the earlier drum. The early hubs are not flat on the back and do not have register on the back. The early drum does not have a hole big enough to go over the back of the late hub.
Andy knows of what he speaks. Listen to him. Here it is simplified: early drums = hubs on the inside. late drums = hubs on the outside. The switch date is not nailed down, but approximately 1942. If your car came with the opposite style, somebody got to it before you did.
