New brake drums - rear T-Cab

[tomnoller]

I have a '62 T-Cab and a spiffy new set of wheels that won't fit the rear drums due to the humpy ridge. (The front drums are now disc brakes, so it's not an issue there)
Seems to me this has been discussed ad nauseum, but I didn't take much note at the time because it didn't matter then. I'm presuming they're 11 by 2" drums with the 5 on 5. If'n someone could point me in the right direction, I'd be much obliged.

It's a half-ton, BTW. Thanks.

Tom, can't remember where I saw it now Stude Truck site maybe, but someone had used a Chev. 1/2 Ton pickup front drum and cut the Stude. hub or the Drum on a lathe to match the center hole size, put all together and it worked fine.
Note that your wheels should be 5 bolt, 4 3/4in. center to center on 3rd. stud from the first. same as Chev. car, 1/2 Ton Truck and small Toyota truck.

I found it for you. It's one of the pages in the Studebaker Tech Help section at Chuck and Chris Collins' Studebakerparts.com. Look down the page for "Truck Brake Drum Help":

Thanks Guys! I don't see why the 1/2 ton should be that much different than the 3/4 in the wheel dept.

I think that they all agreed that the wheels/drums are a 5 inch bolt circle. The 4 3/4 inch measurement was bolt to bolt, an abnormal way to spec. wheels/drums.

Transtar60 and StudeGary; If you've got a tape measure and a 5 lug drum or wheel, what other way to measure is there? I never heard of taking a protractor to the junkyard to measure wheels! LOL Rich.

your locak tire shop may have a plastic fitment tool it's basically a measuring tool specifally for this quest - if you can borrow it great if not - make your own out of even a sheet of paper - just place the paper at the end of your studs and press - instant perfect portable bolt pattern measuring tool

Tom, if your remark was regarding the 3/4ton trucks, there's a vast difference! The Stude 3/4 ton trucks use 8-lug wheels.
The Stude 1/2 truck stud pattern is commonly referred to as "5 on 5"

Studerich I dunno but the Studebaker truck 1/2 ton bolt pattern is 5 on 5.
Chevy passenger car bolt patterns can vary but fullsize are normally 5 on 4 3/4 bolt circle.

Dont know what else to say.

[Guest]

Very strange...the 3/4 ton info on Chuck Collins' website definately doesn't work for the 1/2 ton 7E7. The Bendix number given is a 12" drum for 50s thu early 70s Ferd.
We also measured the alleged 5 on 5 Stude hub and it definately is 5 on 4 and 3/4" but the holes on the 5 on 5 wheels I ordered fit the stud pattern. Huh?
Now I'm on a quest for a 1/2 drum that'll work with my Stude hubs for the rear.

But it says that those numbers are for a 3/4ton truck. He didn't GIVE a number for the Chevy drums that he's used on his half ton (Jerry Kaiser). He just said that they were for a '76 model Chevy half ton. You'd have to tell the auto parts place that and let them look up whatever number it is.
Then there's the little matter of having the hubs machined a bit to fit the inner hole of the Chevy drum. (per the photo shown). I think I'm gonna go that route. I searched far and wide for spacers to let my Riviera wheels sit on the Stude drums. I ended up fudging it in the end and tho it's worked for 10 years now, I've never felt real good about it. Jerry's solution would be THE fix in the long run.

I'm planning to do this, as well. The NAPA guy has 11" Ch*vy brake drums for me (made in Canada or USA, better than what Autozone carries, he says), and he recommended I use a real machine shop to machine the hubs, rather than a place with a brake lathe, which he says are not as accurate as what a machine shop uses.

Oh, and "5 on 5" pattern Ch*vy truck or van wheels from the mid '70s and later will do (you'll need them to clear the Turner disc brakes in front).

Dillo, the letter you can't figure out in Ch*vy is "e"... it's spelled, "Chevy".

No thanks necessary, I'm here to help.
