Technical backing plate ID thread

I go to runs and see many different brake setups. My friends tell me what I'm looking at, but after 68 years I still can't identify just about anything except 40's Ford. I've searched here and with Google. There are threads on specific parts, but I haven't found any general identification posts/threads.

Please post photos of backing plates. Including year(s), front/back, etc. Especially please post other than the '39 - '48 Fords shown below.

I stole the following pix from the "for sale" ads.

Also include interchangeability references if you know. i.e., the below are similar but have small differences. Are they interchangeable?

B-t-w; please don't clutter this up with opinions or criticisms. "Just he facts, ma'am"

THANX in advance.

These are labeled 1942 - 1948 but I don't know if front or back:


These are labeled 1939 (but again I don't know if front or back):

Rear backing plates have a tube that the emergency brake cable p***es through. Ron

 

39-40 have the adjustable bottom mounts, the later don’t

Both sets are ID'd correctly & both sets are fronts.
Rear plates would have E brake tubes for the cable.

 

The easiest way to tell early from late and front to back the little square divots circled in blue are 46-48 and the backs will have a little ******/funnel that the e brake cable goes into in the red area.

ive seen people fill the e brake spot and run them up front

 

Surely there are pix of backing plates out there that aren't the 40's Fords...

 

Not yet apparently.....

 

This is the front of the Frank Mack T. What are these backing plates?

 

Anyone ID this?

 

Or these?

I'm back to early Ford. What are these?


I know they're rear but what year(s)
I had to cut the drum off this one. Anybody have a way to get them apart and save the drum? I don't need to put it on a car, just for mock-up.

 

Very interesting..........

 

Early Lincoln, ‘39 ?, not sure of the year.

 

1941 to 48 Lincoln rears.

 

Thanx @Fordors & @HemiDeuce,

What are the defining details?

 

I do not know how to differentiate years of the ‘39-‘48 Lincoln brakes but what I see first is the Ford axle bolt pattern and the recessed mounting pad, there are three various depths that are the key to exact ID of years.
The second photo shows shallow depressions at 3 and 9 o’clock and below those is a “c” shaped slightly raised area. The last things for me that point to early Lincoln are the two small holes near 3 and 9 for the anchor pins Bendix brakes use and the offset slot at the bottom for adjustment of the star wheel.

 

Thanx for that! I acquired them on a rear end of questionable origin.

 

Here are the differences from left to right, 39 & 40, 41, 46 to 48 Fronts.

 

Thanx again, now I see.

 

Thanx HemiDeuce.

I'm ***uming that these fit onto Ford spindles? Is that so? If so all of just some? Round? Square? Years? etc.

 

A little more detail if anyone is interested.

The 39 and 40's are so deep they will not fit over early Ford spindles.

The 41's are the same depth as 40 to 48 Ford p***enger backing plates and fit 37 to 48 spindles, I like to use the square back 46 to 48 spindles.

The medium depth 46 to 48 Lincoln backing plates can be made to fit the 46 to 48 square back spindles by grinding the upper inside part of the boss on the top part of the spindle, without going into the bushing.

In the past there have been some adapters to adapt the 46 to 48 backing plates to the early spindles, but they move the drum and wheel out, and I think it doesn't look good.

The rear backing plates are all the same as the 41 fronts and can be used on the front with early Ford spindles, you can weld up the parking brake cable holes or leave them as they are.

 

can someone tell me what the radiator surround is off ? ( post 10 ) Thanks.

 

Whippet, I think about 1925. The rounded, semi-streamlined look made them popular on early race cars.

 

I found this in the "Dressing up your I beam" thread (post #7). What brakes are these? Someone on that thread asked about them but there was no response.

 

Something else besides 39-40 Ford brakes? How about the once popular '55 F100 brakes, shown in their natural habitat, on the floor waiting for me to trip over them (again).

 

Atch,
I believe that those are called 'skeleton' backing plates. Used on oval track cars. They were originally steel, later aluminum. Frankland was one supplier. The brakes were likely Buick as the finned drums would indicate. May well be Wide 5. I have never seen them used on the front, but there are a lot of things I haven't seen. I'm a rear end guy

Are F-1 and F-100 the same?

Thanx man. I like them. I'll probably never see a set in person, though.

 

You could, I’m putting together a Quickchange with those plates and drums.
It will be for sale
Start saving
This one is truly one of a kind
