Brake Drums

International R120 truck, 1954, with the wide 6 lug wheels and 12 inch brakes. Anyone know of a way to build up brake drums? The rear drums on this truck are worn to the limit. I would run them, but they are rough due to failed linings and I can't take more out of them. Would flame spray be an option? Needing to repair them if possible because they aren't replaceable realistically. Only used pair I have found that are good, they know what they have and want $1100 each for them.
 
Good idea,, but the problem is the lug pattern. Would have to do front also, which leads to steering, which leads to brakes, which leads to..... Not streetrodding it, trying to keep it stock and at its factory GVW.
 
I would gladly pay a $2-300 for a pair of uncut, machineable drums. Problem is, they don't exist, have been obsolete since 1968.
 


I've mentioned this idea on the IHC truck boards- there are small foundries that can cast them up for you. Might want to have a bunch done and sell them to pay for the project.
 
The link leads to a Ford drum, but there are many options. The key ingredient I am discussing is that it would be way cheaper to buy a drum that has the 12 ID and appropriate shoe width and offset from hub mount new, then re-drill and turn the center as needed. It might require welding up existing holes, or making ring spacers, but way less expensive. My GMC has 12X2-1/2 drums with about 3/4 inch offset from hub face to shoe contact. 1949 through 54 3/4 ton PU. It has 8 on 6-1/2 holes. Jim

Do you have the silly huge bolt pattern? Ive got a two wheel trailer here that has an IHC truck rear end under it. I use it behind the tractors so I dont need the brakes. Dont know what they look like but I sure could pull it apart and see what I got if your interested and not in a big hurry.
 
I imagine you have checked, was wondering if late 40s KB models use the same drum. Have some KB-7 models here. Or are they a stand alone model that you have...Dad had about a 52-3 model 120. Are any year IH trucks compatible?
 
I have no idea where to fiund any. Just want to say had same problem back in 1977 with a 1849 Chevy 3600 series 4/4 ton truck as drums were not avaiable for it at that time. And it was nly 28 years old at that time.
 
I have no connection these folks but they may be able to help. They line drums.

You might be able to re works 12X2 drums from GMC Jeep Ford etc but bolt pattern is wrong on all of them. Center hole probably too as I think you have R1070 IH differential. IH used R1070 for years but with various brakes.
1979 Ford F250 had 12x2 1/2 brakes. Please post back if J&G shows promise.
 
I wouldn't push the Panic Button just yet. If you don't have to have it done in time for the St. Patrick's day parade and got some time to work with, I'd keep looking.
That one guy you found that has some for $1100. That is still his asking price. He (it sounds like) won't take a penny less. But, that doesn't exactly mean he'll get that. Hard to say how long he'll be sitting on top of them before he gets em sold. Or sitten on top of them already, for that matter. At that price.
Local junk yard here, over the years, set older more complete stuff off
to the side. Exceptionally nice and complete (restorable), they wouldn't strip out. Over the last 10 to 15 years, they have kind of phased themselves out of the parts buisness, and not parting out these newer vehicles. Got more into just smashing vehicles as they come in, and selling iron. Still got thier old bone yard. Hard to say what all is sitting in there. Same people run it. Doubtful they smashed the stuff they once set aside. Not the type that would do that.
Another place sold out last fall. Had tons of parts from 50's/60's. Mostly just individual parts. Very few complete, or picked over vehicles. The place evidently was the type to dis-assemble. Keep the good, scrap the rest. Anyways, problem was, nothing was really marked. Kind of, just auctioned the parts that way (seller deceased). The stuff that was visually recognizable (make, model, and year), brought good money. The stuff that you couldn't, not so much. Kind of one of those deals where, a 68 such and such car is easily recognizable. But take the hood off, and set it off by itself someplace, and then try to recognize that.
I'd keep looking.
 
Are the drums right at the max? If so, you probably can take a cut just to get the drums cleaned up? A shop here would go above the limit just to clean the drums. The old mechanic Would say these old truck drums are so thick a few thousands over will not hurt a bit. I doubt a shop will do that today though. Stan
 
Have you tried Old International Trucks .com? First link is for a set of rear drums for about $140 ea. ..may be Can. $.. but they only fit up to the r110, they are 12 x 2. I am going to suppose it is a bolt pattern deal between half - 3/4 ton or something of the like. I would suggest contacting them, however they are in Canada. Second link is for the Binder Planet forum, might be someone in the know there. If you do go there you will quickly find out what an add supported forum is like.

Don't know where your from But around here i would go to my go to place for TRUCK parts , I would start at Commercial Truck and Trailer . They have been around i think since the Wheel was invented . At one time we had many places around here for big truck parts but due to the decline of the owner operator so have the souses for truck parts. Also Alliance Motors a one time Med. duty I H dealer . Then the fact is that truck brakes are NOT brand specific as it is more to WHAT REAR AXLE you have as it could be a Rockwell, a Spicer timkin and also what rating as to LBS. it was designed for . Then what can you update to as what will match the spider . Of a fast way out is it a round axle or a square axle and a gas ax and four new U blots and maybe a yoke change on either the drive shaft or the rear end and wham bam thank you mam and you back on the road for less then the cot of the wacko wants for his stupid drums . And by doing so you can come up with a gear ratio more suited for play then work and highway driving . Just a thought . Also with the amount of Medium duty trucks in truck bone yards you could swap out ft and rear or more modern axles with disc brakes for the price of those drums.. And while your at it you could be nice and send that guy a large box of Salt and pepper so he can enjoy chewing on his paper weights.
 
Sounds like a time to just swap out the whole rear axle for something more common and use that. A picture of the wheels would be good. If they are what I think they are there were some Fords with a similar wheel and Dodge had some in 16 inch for one ton Ford was a 20or so with a 6 bolt in a large pattern. if you could find an axle with either dayton wheels or air brakes the drums would probably be a lot more common to find. I have a pair of the RA351 or something like that in an old cement truck. Air brakes with dayton wheels.
 
Supposedly 53 to 67 Ford F-350's also used the six bolts on 7.25 inch wheels
One ton Dodges even Studebakers too and early power wagons.
M714 military trucks.

Those likely all used Dana rearends and many of the brake drums may interchange.
 
You might look to see if there is a disc brake conversion kit for that truck. It would solve your problem plus give you better braking ability.
 
If you have a good machinist and since these are rear brakes I would contemplate machining a ring to be shrink fit into the drum for a new wear surface.
You may want to do this under the cover of darkness as I'm sure this will be frowned upon here.
 
I took a drum and everything inside of it off of a one ton international pick up and put it on a 1964 Ford one ton truck. Everything fit and the brakes worked fine. I say one ton IH pick up because it did not have dual wheels on the rear. So if it will work that way, it will work in the reverse of that. I think the axles were identical.
 
(quoted from post at 06:35:51 02/12/22) I would gladly pay a $2-300 for a pair of uncut, machineable drums. Problem is, they don't exist, have been obsolete since 1968.

It always strikes me as funny when an old truck part is obsolete and unobtainable, no big deal, but when an old tractor part is obsolete and unobtainable, everyone has a conniption fit.
 
Thanks for the insights. I'll call J&G on Monday. The problem with retro fitting another drum is the drum offset, about 3.25 inches from the the braking surface. I have yet to find an off the shelf drum that deep. This does have the wide 6 pattern.
 
A guy on an IH forum I'm on just had a company in McHenry Illinois do this. Machined and sleeved the drums and re-lined the shoes. Said it was $1,900 for all 4.
