1940 brake shoe differences

[Duke]

Hi,
I have three different designs of shoes.
The black set has ford script on both shoes, both shoes identical.

The second set of fronts have Ford script on one shoe, the shoes are slightly different.

Third set (with the e brake), no script, part that goes into wheel cylinder is thicker.

I am planning to drop a set off to be relined for my rear brakes. I am thinking the brown set without the e brake is a correct pair? Set 2

Thanks

There was a post here about the point into the wheel cyls being wrong on some newer shoes. Newc

I have read about aftermarket stuff being off. That is why I am concerned. I also thought that the forward shoe was different?

The shoes themselves (forward or rearward) are identical. The shoes are also identical front axle to rear axle.
The length of lining is different. The forward shoe has a longer lining than the rearward shoe.
There are many aftermarket shoes that are too thick. The issue this additional thickness creates is at the bottom - where the plate captures the shoe(s). The plate will cause the shoes to bind.
I'd strongly suggest you have the Ford script shoes lined. If you must use other than Ford shoes, measure the thickness at the lower area I'd mentioned and compare to a Ford shoe.

The thing that concerns me on the black Ford script pair is the lining is the same length? They have been relined.

Linings can be cut back to the next rivet if they have all been fitted at the long length.

Mart is correct (post #6). Apparently, whomever had lined the shoes did not do so properly.

[Duke]

Is there a length that they should be cut to?
Thanks

Just cut it back so there is as much sitting past the next rivet as there is now sitting past the last rivet.

I showed me rivetting some linings in one of my videos. It might help you see where the shoes need cutting back to.

Mart,
That did help. The rear shoe lining is way shorter. Funny that I have three sets off two different cars and all the linings were the same size.

I too have seen lots of sets of shoes the same size, perhaps cheaper aftermarket parts, I don't know. While Henry probably designed them correctly, I highly doubt you would notice any difference in braking with both shoes long. I would have just put them on myself.

I think the reason for different length linings is to equalise the wear; the front linings do more braking than the rear, consequently have longer linings.
