Drum, no swage?
This weekend I replaced the cross shaft (thanks for the work Will), and all brake rods on my '30 Tudor to eliminate the slop.
I had been hearing a popping sound sometimes after releasing the parking brake and backing out of the garage, so I pulled the left rear hub off to check on things. I was surprised after taking off the wheel and installing the puller, that the studs were not swaged. After the hub was off, I discovered the studs had been tack welded in place on the inside of the hub and ground off flat. I did not find the cause of the pop, but think it was solved when I sorted our the mess with the return springs. There was not really any great improvement in brake performance, but the pedal felt more "solid" when applying the brakes. I think cast iron drums are in my future. The brakes looked good on the left rear. I have some spare used hubs and backing plates. I should call Randy Gross, but I'm hoping I could send him enough stuff to use and he could fix me up. Is not having swaged studs a big concern, or is it ok for the short term? Thanks Quintin |

Re: Drum, no swage?
Looks like mine were done that was in the '80's. When I went through the brakes for the trip to NY I noticed the welded in studs. Changed them out and had them swaged.

Re: Drum, no swage?
I don't see it being urgent, but I'd also get them swaged. If you're getting cast drums, then wait and do it at that time.

Re: Drum, no swage?
It does depend on the weld quality . I have had welded studs where the weld has failed so the hub had to be pulled . OK if you are at home but no good when you get a flat out on the road !!! . Welded studs are fine if done well and clear the emergency brake carrier . I change them if they look suspect .

Re: Drum, no swage?
The hole in the center of the drum seems to fit the raised flange on the hub almost perfectly. Its put together just like a modern car with drum brakes. The shoulders on the studs fit just slightly loose inside the stud holes in the drum. The wheel and lug nuts keep the drum on. It could be some of the noise.

Re: Drum, no swage?
James is right... if the drum is not secured by the swaged studs, it can "work", and play all sorts of merry hell with the studs, drums, hub, brake adjustment.

Re: Drum, no swage?
If there is play (movement) within the drum and hub set-up, then this movement will eventually shear the studs off and you will be in trouble. I have had a few jobs come in where the studs were welded on the back side of the hub and all five studs broken off on the outer side of the hub. These same jobs had the backing plates flattened by the road surface after loosing the wheel and drum.

Re: Drum, no swage?
Agree with Mel, once the studs have been welded on the rear it renderes them useless.
I would look for good hubs and send them all the Randy to have them mated and done. Do not half do brakes... you will regret it at some time and point.. probably sooner than later. Larry Shepard |

Re: Drum, no swage?
I just had Randy do two front drums for me. I could not be happier, he is a gentleman and does fine work. NFI.

Re: Drum, no swage?
I'm out of line again here! .... had lugs expertly welded on one of the rear when on tour in France many years ago... its been perfect ever since.. I see no reason to get them altered.. agree with #5 ....perhaps the quality of welding is better here in europe!!
