The left front brake on my Adventurer was hanging up and I wanted to check all the wheel cylinders, so I jacked her up and attempted to remove the wheel and tire. One of the lugs just spun. Uggh! Upon further inspection it was the only stud without the telltale "L" on the end, leading me to believe it had been replaced at some point. I pulled the cap, cotter pin, castle nut, washer and nut to remove the whole wheel and drum assembly. The uggh got worse. Some moron had indeed changed out one of the studs and must have stripped the serrations in the stud hole on the drum before doing a very poor job of welding a right threaded stud in its place.

I called my aunt, from whom I received the car and asked about the repair. She remembered my uncle being upset about someone snapping off one of the studs because he didn't check for the left handed threads when he had the tires rotated. As she remembered it, the mechanic who broke it also told my uncle he'd fixed the problem. A pretty half-a$$ed fix, in my opinion with the wrong parts. I know he couldn't have told my uncle about the abortion he performed on it or there would probably have been a trial for homicide over it.

So now I have at least one brake drum to purchase because of the stripped serrations in the whole. I wouldn't mind just having to replace the stud, which I was able to get out with little effort, a vice grips, a socket and ratchet.

Anyone have a lead on drums for my 1960 Adventurer?

I will be calling you. Are you open for business on Saturday?

The studs need to be pressed in and swedged to keep them in place. Is this something you can do ?

If not, I recommend calling John Fowlie at Big M auto parts. The 12" drum you are looking for is the same for all senior models (Desoto, Chrysler, excluding Imperial) 59-61. Part no. 2084799. Also, I would recommend against using asbestos shoes, for obvious reasons.

The hole where the stud goes into the drum has been totally stripped, unfortunately. While I am doing everything possible to keep the car as original as possible, common sense about safety - especially with brakes - has got to win out over originality. I'm going to replace all the components in the brake system just to be sure she stops when I need her to do so. The issue with the drum was the tip of the iceberg, as the saying goes. I pulled the wheel cylinders from that wheel last night and, while I believe they might be rebuildable, I'd rather be safe than sorry.

Thanks for the heads up on the great service available through Jim Fowlie at Big M. Its always helps to have another source for labor and parts.

Craig has been very nice to me in his reply and even took time while he was at a show in New York to call me about the parts I need. It looks like he and I will be doing some business at either Carlisle or Hershey in the very near future for the parts I need.

For the stripped serrations you can probably find a lug stud that has a larger diameter at the serrations. Measure the hole and the lug stud dimensions then check with Dorman for a possible replacement.

Morning Mike,

As tempting as that is - and temptation to go retrorod is always biting at my heels - I'm trying to keep the car as stock and original as possible. I do agree that the discs would make stopping a whole lot more comfortable but the direction of the re-build is pure bone stock.

Morning Chizler,

Thanks for the info and the chart. That chart has already joined the electronic library and a copy printed on card stock is in the binder in the garage.

I believe I'm going to replace the whole brake system with stock components to keep the car as close to original as possible.

Thanks a million for the assistance.

Hey Todd, Craig Here, on my tablet at Fall Carlisle....
We didn't discuss wheel studs -- but I actually have Front & Rear,
Lefties and Righties -- if you want to keep THEM original, too.
I have to go beddy-bye, I have had 5 hours of sleep these past
3 days -- and call me addicted, but while my eyes are still open,
I thought I'd look in on my 28 different classic car forums for any
Important potential messages!!!!
Talk to and see you soon, Yours, Craig.......

Hey Craig,

You have been most kind and courteous. Never worry about sounding off about things. we all need to vent a bit and who better to vent to than your friends.

I will need the studs and would like to keep the car authentic with left and right studs.

I'm pretty stoked about getting up to Hershey, meeting you in person and filling that wagon with Desoto parts for the Adventurer! Have a great time at Carlisle. Would love to have made that show, too, but that insignificant thing called work always gets in the way of my Desoto time.

Hi, I know I'm a newbie to the FL world and I'm no ace mechanic, but this same exact thing on my 70 Road Runner some years back and we were able to save the drum.
Once the stud was removed, my buddy welded the hole almost closed. slowly building it up so as not to warp the drum. Once we had sufficient material, we slowly drilled out the stud hole on a drill press
gradually stepping up the drill size until it was slightly smaller than the original size of the stud. We then PRESSED a new stud in place, not hammered it.
It's still in there and has never backed off or given my any problems. Just my 2 cents.

Yes, this is critical. But for those us without a press or access to a machine shop, it would likely cost as much or more for a shop to perform the procedure similar to what Forgotten 61 has described as it would to get one from Big M or someone that has done a disc brake conversion. And if the shop applies too much heat in the welding process, the drum will warp and it'll be toast.

An alternative to pressing is to use the threads on the stud itself to pull it into place. Push the stud into place and then use a spacer like a socket to start the nut on the first few threads and then tighten the nut to pull the stud in. You might have to change the depth of the sp0acer as the stud is pulled in.

When using this method it's wise to check the nut torque a couple of times in the first miles.

I'm sure you have heard it and thought about it over and over but front discs will not harm the value of a stock car as it's easily removed and drums put back on. You gain a nice level of safety and over the counter replacement parts. Many die hard OEM guys will agree.
