Brake Spring ID 1938 one ton p/u
 

I'm looking to replace all brake springs on my '38 one ton since some are not serviceable. There are 4 unique springs (originally color coded) both front and rear - no duplicates. I've found some springs but still need to identify the following two. I need the ID of the rear black spring - 5 1/8" total, coils 2 1/2" and diameter 5/8" and the ID of the front green spring - 4 1/2" total, coils 2 5/8" and diameter 1/2". I haven't yet found them in the Green Bible. Pictures of front and back wheels attached. If the pictures are too small here, I can send larger directly.
Thank you.

Is this a 122" WB? Do you need the Ford part numbers? Such as rear 81T-2034 spring-shoe return-adjusting side 122"rear, need 4.
front 81T-2296 adjusting side, need 4

Terry,
This is a 122" WB. I'm looking for Ford part numbers such as the ones you indicate. The 81T-2034 are the front red return springs, and I do have 2 of those which is all. The 81T-2296 are the rear red return springs which I am still looking for 2. Between the front and rear there are 8 different springs. The front drums are 12" ID and the rears are 15 1/4" ID.

According to the Service manual the 1 Ton front brakes use the passenger car housing plate assembly. The rears use the 1 1/2 ton front housing plate assembly.
The 78-2297-A black spring may be used on the fronts, as well as 78-2297-B , orange.
The parts books are very confusing as to what spring goes where.

Terry,
You can say that again about the parts manuals being confusing or inconsistent. I really appreciate the additional information. I have in hand 78-2296-A (black) and 78-2297-B (orange) for the front as well as 81T-2034 (red) and 81T-2035 (green) for the rear.

Interesting photos of the mechanical brakes on a large truck. Thanks for posting them. The brake replacement on my Tonner was a piece of cake compared to that system. Good luck with your hunt....

Have you tried JobLot? http://www.joblotauto.com/ They had all the brake components for my Tonner.

Re: Brake Spring ID 1938 one ton p/u
 

Thanks for the comments. I got everything that Job Lot had. James over there has been wonderful to work with on a number of items, and like all of the good guys I've worked with, he's suggested other sources when they didn't have something.

Beside Job Lot look to Southside Obsolete for the springs. If you can take a photo of what you need with dimensions and email it to Fred.

Re: Brake Spring ID 1938 one ton p/u
 

I did check with Southside, but Fred didn't think he had them kicking around. Without numbers it was difficult to know for certain. I am posting photos here with measurements for both of the springs that I am trying to identify.

78-2035-D is green and 4.87" OAL. It is not listed for a truck application.

Re: Brake Spring ID 1938 one ton p/u
 

The green parts book only list two springs for the front of the 122"
78-2296-A & 78-2297-B are both listed for the 122" Front brake shoe retracting.
78-2297-B is orange 4.75" as shown below and 78-2296-A is black.

Re: Brake Spring ID 1938 one ton p/u
 

The green parts book list four springs for the rear brake shoe return.
81T-2296 on the adjustment side, 81T-2297 on the operate side.
81T-2034 on the adj. side, 81T-2035 on the op. side.
For the shoe operating lever retracting it list 81T-2036-B shown below
Are all 5 of the rear springs different?

Re: Brake Spring ID 1938 one ton p/u
 

yes he tried me when he was first looking for springs and I told him what I had. his measurements did not match up with what I have which still have either ford tags or in ford bags. He did buy the collapsible springs terry pictured and two rear n.o.s. axle bumpers. since then I have sold other people springs for the 81T off his original want. I suggested to him that someone may have switched them in the 50's but he was sure that was not the case. If he wants to come back to me I am willing to work with him. I have the springs and only n.o.s. Fred

Terry and Fred,
Thanks for all of the information. Yes all 5 springs on the front are different and all 5 springs on the rear are different, and the front and rear are different from each other. Terry, it appears that you have identified the rear spring that I am still looking for a pair of as 81T-2296. I also appreciate the number on the rear operating lever retracting spring. I'm still looking for the identity of that same spring on the front. I also only found 2 springs listed for the front: 78-2297-B and 78-2296. I still need one of the 78-2297-B. The spring that you picture as 78-2035-D certainly looks like one of the front springs that I'm trying to ID although it could be very slightly longer. Fred, we'll be talking.
