'39-41 Lincoln brakes

[russcc]

I have collected some original parts for possible future installation of '39-41 Lincoln brakes on the front of the '40.
Questions:
1. Are the front & rear backing plates the same with the exception of the E brake plate that is removable on the rears ?
2. Do the front & rears use the same wheel cylinder ?
3. Does someone have a photo of the original drums as I may have a source for them, but I am not sure what they look like.
I am not interested in any of the reproduction Lincoln brakes, I know all about them, so please don't take up space with those comments. Thank you. See photos of rear backing plates.

Rears work better on the front because they are flat no offset.

The wheel cylinder, you need to use one thats compatible with a rubber hose and copper washer. Rear wheel cylinders use a hard line with a inverted flare seat.

The lincoln drums are flat compared to a 40 ford and you need the matching lincoln hub.

I use 40 ford drums hubs with original rear lincoln backing plates and fill the e brake cable hole

'39&'40 lincoln brakes was one application, '41only was another application. The '41 only is significantly different in offset. Good original drums are going to be a challenge to find.

As stated; rear backing plates with the holes filled or '41 only fronts. The offset of the others are incorrect.

'42-'48 fronts can be used with a machined spacer if you have the capability; otherwise not worth the $.

Ford hub and drums are the way to go.

Isnt the early lincoln fronts 39-40 , they have a narrow spindle bolt pattern like a 32 to 36 spindle?

On the rears, they are the same 39 to 48?

That is correct.

russc ...... Here is another picture of REARS, clearly showing the offset to be the same as Ford FRONTS, therefore....usable! The BIGLY picture on bottom...(SORRY)....shows the THREE different offsets for Lincoln FRONTS. The '41 is obviously the only FRONT that works without the aid of spacers.
Hope this helps! DD

Thank you all. It looked like the 40 drum would fit the '39 backing plates I have. Good to hear they work. So did I understand it correctly, the '39-40 Lincoln fronts won't fit the '40 spindle. On page 59 on Vern's book on "Building a Traditional Ford Hot Rod", he says that the '39-40 Lincoln brakes fit the '37-46 Ford spindles, and assume he means the Lincoln fronts. Also, I forgot about the brake line connections being different from front to back. Anyone have a Lincoln or aftermarket part # for the front wheel cylinders ?

39-40 Linc front backing plates have the deep offset [almost the same as 35-36 Ford], and the same spindle bolt pattern as 35-36. By using a spacer [from memory, about 3/16" thick], those 39-40 Lincoln plates can be used on 35-36 spindles and 35-36 front drums. However, with the deep offset, you'll not be able to use them on 40 Ford spindles/drums.

It's not that the '39-'40s won't fit the spindle. The offset is so pronounced that the shoes would be exposed....in other words, the FORD drum can only go on so far. But with the radical offset in the center of the backing plate, it would APPEAR (seem like) that the drum needed to go on farther. If that offset is different than Ford Lockheed, the shoes are gonna be in the wrong place when compared with the drum's shoe contact surface. DD

It could be that it wasnt noted fronts or rear. But you got rears so with 40 spindles and drums your safe.

The only real thing about using lincoln drums /hubs is they set the front tire track width alittle narrower and they have fins.....or just bragging rights. I sold all the ones i had and kept all the 37/39 and 40-48.

As for the wheel cylinder, i think you can use the F100 wheel cylinders which are 48 to i think 66 F100 pickup. Not sure if the 40 hose works on them. The F100 hose is for 3/16 hard line and the 40 used 1/4 with the special banjo fitting on the front left side. So you might have some plumbing to deal. Maybe not

I believe you are correct - I seem to recall that for my ioriginal 1940 Lincoln brake install a spacer was used and my original stock 35 spindles were retained. I also recall that the bolt holes needed a bit of tweaking to align properly with the 35 spindle. Here is mine - note the forward cut out for brake cooling with scoop removed and then installed.

WC18290 & WC18291 these have 1-1/8" bore.

F-100 wheel cylinder WC9090 WC9091 mentioned earlier will also work; but have a 1-1/16" bore.

The difference may be useful for brake balance depending on your set-up.

Both these have 3/8"-24 inlets; BH16179 hose fits the cylinders and has a 7/16" female end to fit the Ford brake plumbing arrangement.

Decent looking brake set-up.

I don't see a bearing on top of the spindle; it appears you are using Torrington thrust bearings. If so, how are they holding up? What maintenance have you found to be required?

Thanks for sharing that.
Save me some time next time i do a brake job.

Steering setup is performing well - no issues or special maintenance that I am aware of ... save normal grease at the zerks.
