Hot Rods Finned brake drums

I just ran across some finned aluminum brake drums. Are these desirable rod material? If they are, should the spindles and hubs also be saved? What about complete rear end?

 

That's a very vague question. A little more detail would help. What are they off of, pictures, etc.

 

Yes, pictures would help a lot.

 

The car I'm parting out is a 68 Buick. I thought the 430 motor and TH400 trans would be good hot rod material. The front brake drums are finned aluminum. I just pulled the rear wheels off and they are steel. I was hoping to find a posi under it but I didn't get that lucky. I've been saving parts for years to build a Deuce style hot rod. I got a banjo steering wheel and a deuce grill. I thought this drivetrain would be cool yet different. I'm picturely handicapped right now, that keeps me from posting more. I'll try to get one of the grandkids to help in that respect.

 

12 inch? what's the wear? not really worth it if they're much over .060 out

45 fins are desirable but some people use the 90 fin version

fronts, for hot rods, just need the drums
rears, helps to have the backing plates also

 

You also need 46-48 front hubs to mount the drums on the spindles. When driving out the Buick studs, use some pipe or socket to back up the hub. When removing the Ford studs, use a 5/8 deep hole saw. The swedge cones will start spinning and you can’t drill too deep. Enlarge the center of the hub to 4.000. If you do a good job of centering it, you won’t have to rebalance the drum. The aluminum must be removed behind the brake surface to the depth of the original machining. DO NOT REMOVE ANY IRON BRAKE SURFACE!!!
You want the lip on the OD of the backing plate to fit in behind the brake surface.

 

I don’t think the 68 Buick brakes are the 12” drums that are useful with early Ford brakes. Can the OP measure them?
