Help Identifying Early Ford Juice Brakes

[29Coupe]

Hey guys and gals,

I could use your help identifying these early Ford juice brakes.

Any help is greatly appreciated.

Thanks!

40 to 41. The anchor adjusting bolts are missing.

Hi these are 1940-41 and someone has drilled holes for another bolt pattern, as the other BILL stated someone has replace the anchor bolts with regular type bolts.

The hubs look odd. A 1940 O1A hub has raised bosses for the studs. The bosses had a raised side and the studs were flat on one side. The hubs may be F1 or something off the wall. A side view would help. I agree on the drums and backing plates.

Thanks everyone for the help!!

Here's some more pictures of the hub. The hub does not seem to fit the 1940 spindles that I have. So perhaps they are off something else???

I might be wrong, but I get the feeling the smaller bolt pattern is the correct pattern for those hubs, and someone drilled the wider pattern trying to use them in an early Ford application. If they don't fit the spindles that might back up my hunch. The bearing numbers might give a clue.

Mart.

If they are F1 they would require a different inside bearing.

[Andy]

Mart is right. They are something odd. They are NOT F1 or F-100. Maybe later pass. car?

Pickups stayed 5 lug on 5 1/2" circle for a long time.

Backing plates are 39-42 design.

I just had my 40 rear backing plates and drums off. Mine looked the same as those pictured with the exception of the e-brake stuff and the modern anchor point bolts shown. My drums looked the same but they didn't have the larger lug holes in them. Not much help but that's all I have.

Using these 39-48 Hydrolic brakes on a Model A or other light car, works pretty good with a marginal safety factor. However, using them on a later heave yer cay is not beneficial for today's traffic. Up grade to a disk brake setup.

Thanks everyone for all your help!!
I really appreciated it.

I doubled checked the bearing numbers as recommended by Mart.
They were correct for that spindle.

I took a bit of emery cloth and polished up the spindles a bit and the hub now fits!

Looking at the "X" marks adjacent to the holes with studs, it's appears that the hub flange has been marked for re-drilling to the larger pattern, suggesting that these hubs perhaps were not originally 5 x 5-1/2". But for the life of me, I can't think of any drums/hubs that will fit a Ford spindle (especially 12") that had a smaller than 5-1/2" bolt circle. DD

I tried measuring the picture and did some math on the original bolt circle. The crude answer was 4.40". It could be a Ford passenger hub as 4.50" is close to what I estimated.

[Andy]

I had a Mullins trailer. It originally came with 6 lug Chevy hubs and wheels. 40 Ford hubs fit right on like stock and allowed the use of Ford 5 lug wheels. I think a lot of early hubs used the same bearings.

The measurement from the shown stud-to-stud is 5-1/2".
The other holes measure 5"
