Installing new hubs/studs/drums

[Leatherback 57]

Hi
Is there a process to press in new studs into new hubs and install new drums on a 1930 coupe? Heard it takes a lot of tonnage to press in and swedging of the drums?? Any info would be appreciated. Gary

It takes approx 30 tons of pressure to do it RIGHT. Less than 30 tons - when done may look right and feel right, but, under load driving down the hwy _ are they tight enuff.


Secondly, The hub and drum should be in perfek contact. The new drum will be straight and true, but is the hub straight and true to match the new drum, within .001 of inch I put the hubs on the lathe and retrue them. Them swedge the hubs and drums together.


Tird. The hub, drum and swedging tool and the press MUST be at prefekly (sp) square to one another or you will crack a hub or drum.


This is not a project for the faint of heart or for someone that has not watched the process. You have the best in the man in the business right there in southerrn CA. Randy Gross. My recommend would be to contact him. He sell the drums and does a fantastic job on the swedgine, shoes and any other part of brake work.

The hubs are very tough because many are out of true and need to be turned. Some can even be so bad that they are unusable.

There is so much that goes into a brake job on a model a, you really have to know what you are doing.

I took mine to automotive machine shop recomeneded by other guys in my local chapter. They were turned a bit after swedging. Love my cast iron drums.

I did the new cast drums and new studs I have a 40 ton press and I made an anvil setup just to do the swedging. I did the four drums and had them trued up when I was done swedging three took very little and the fourth took a bit more cutting to true up. Cast drums are worth the money and I relined the shoes with webbed lining softer than the molded.

Is there anyone in the San Jose area that can do this? Sounds like it is better to have someone experienced and right tools.

It is not just that simple.

Yes, it takes a special tool set to swedge the lugs. But that is only the begining.

Can you cut the drums round?
Can you cut the shoes to match the drums?
Can you set up the backing plates to thousands accuracy so the shoes will set in the correct place?
Can you get the shoes on center?

To do all the above you need experience and special tools that cost $$$.

The smarter choice is to send them out and have the backing plates set up to the drum by one of many shops with a good reputation. Then you just have to bolt it all together. Once done you should have great brakes for the next 50 years or so depending on how much you drive.
