The Ford Barn

Bill T · 04-12-2012, 08:32 PM

I am replaceing all 4 brake drums with new plasmeter cast iron drums with correct new lugs to attach them to original hubs.

The instructions that came with the drums say to put the new hubs on the original hubs and swedge the lugs tight. Then take the drums to a brake shop and have them true up the brake surfaces on a brake lathe. the new cast iron drums will require turning after pressing in the hub lug bolts.

I can see how the fronts will chuck into the brake lath, but, how do I chuck the rear drums with hubs mounted into the lath and turn them straight. Brake lathes I have seen have chucked the hubs betwee two cones that keep them straight and centered. The model A rear hub is too narrow to accept and fixture that I have seen. What am I missing?

Thank you, Bill T

You need a tool that is older.

The Barrett drum doktor has a smaller arbor that will go through the rear. The bearing side needed the bearing to be installed and the adapter installed.

You can see in the pictures the hub with the adapter partially inserted. I also included the measurements of the adapters on a sheet so you get a better idea of what is needed.

The Brake shop has to have a brake lathe with the small shaft in order to mount and turn the rear drums. Not all brake shops have the small shaft machine. You might have to do some phone calling research. Talk to someone in your local club and find out where the club members have thier drums turned.

I have not tried this, but can you mount the hub with drum on a good spare axle and do the turning on a regular machine shop lathe?

Hi Bill

Find a shop that can turn the rear drum's of the old VW bug's...I used to do both with the small arbor we had at my old shop...If they can do the bug drum's,,they can turn the "A's" Rear's

Hey Bill,

Forgot to add,,When turning the rear "New Drum's" you might want to check the E brake area of the drum...If using new Emergency brake linning,I think it's too thick...I cut the drum to true it up & make the E- linning not drag..How much,,You have to check to see how the drum goes over the E-linning..You might be Ok...

Greg,

Thank you all for your comments and help. I went out this morning and found an old machine shop with an old machinst (I can say that, I am old) and he had exactly what you are talking about. He had a drum lathe with a spindle adapter made to do old ford brakes.

Thanks again, Bill T
