57 Dodge D100 Rear Drum Brake Hardware

[elane352]

Morning, 

 

I have a leaking rear wheel cylinder issue. Given that I am going to replace the upper and lower cylinders on both wheels, I will replace the brake shoes also while I am in the area.

 

Does anyone sell the remaining hardware pieces as a kit? I was able to purchase one for my 64 Chevy C10. I was hoping there was something similar I could use for the 57 D100.

 

Also, I was toying with the idea of a rear end disc brake conversion. Has anyone performed one for a 57 D100? If so, what kit did you use? I attached a picture of my rear end. Am I wrong in thinking that it is 8 3/4?

 

Although I installed a RamMan front disc brake kit, I do not want to do additional business with the RamMan.

 

Let me know what you know please.

I apologize for the upside down picture.

I was afraid there was a horrible accident for a sec

I could be mistaken, BUT that looks like a Ford 9 inch….. which would then create a whole new list of questions.  Have you had the drums off to confirm it is a Dodge set up?

[elane352]

I do plan to remove the drums on Saturday when I am back in town where the truck is. I will respond back then.

Good Morning & Merry Xmas!

 

I removed the rear driver side drum for the first time since purchasing the truck. I was surprised.

 

Instead of seeing upper and lower wheel cylinders, there was only one cylinder (see the attached picture). This setup looks similar to the one on my 64 Chevy C10.

 

Given this picture, and the initial rear end picture, is it a definite that I have a Ford 9 inch rear instead of a MOPAR rear end?  If so, how can I determine which wheel cylinder, and brake shoes to purchase?

 

Thank you.

Need to see the pinion end to really know.

Here is the pinion end picture.

Kinda hard to see with that shield in the way and dark photo, but it sure looks Fordish to me.  8 and 9 inch look a lot alike, the oly way I can tell is the lower bolts that hold the center section into the housing.  If you can reach all of them with a socket and ratchet, it's an 8-incher, if one requires an end wrench it's a 9.

Ford 9".  Getting harder to find and more expensive.

 

Nothin' more to say.  The brakes also show that.

Okay Ken & DJ, thank you and understood.

 There should be a casting number on the wheel cylinder that will translate to a viable parts number.  Depending on where the brake line enters the cylinder, there may be a different number for left and right when offset or two the same number when centered.  Measure drum diameter and shoe width for shoe replacement.  Nine inch axles also came with two different size axle bearings,, 2 1/2' or 3'' if replacing seals.  Four bolts and the axles and backing plates come off.  With that information, you should be able to narrow down a make and model to obtain the rest of the missing hardware.

 

 

Assuming it's a 9 inch, odd that it's set up as a manual adjust.  Shoes, cylinder and hardware look fresh.  A 'W' in front of the cylinder casting number will give you the Wagner number.

Forgot to circle back and thank you for your insight Dave. Much appreciated.

Were you able to narrow it down some?

[elane352]

Hello D

I did pull off the brake shoes and wheel cylinders this morning. I cleaned the wheel cylinder and still did not see a casting number. I have attached two pictures so you can see what I mean.

[elane352]

Disregard my last posting Dave. I hit the send button erroneously before finishing up my sentences. I did not get my pictures uploaded either. I will get things right on the next attempt.

Dave,

 

I have things together this time.

 

I removed the leaking driver side rear wheel cylinder this morning. Even after cleaning the cylinder up, I could only see one character. If additional casting characters are there, I am missing them. if you blow up the picture with the wheel cylinder standing up, you can see the single character.  I am going to have to do some research to see what fits. If I go the Amazon right and they do not fit, I can always send them back with no hassles.

 

I will measure as you indicated regarding the brake shoes. I did see the following number scheme on the brake shoes;

 

8P140842EE  ==> at first I thought that the character after the letter P was the letter l. I think it is the number 1.

I look forward to any comments you have.

   Go to Rockauto and look up 1978 Ford F-100. the wheel cylinders look like yours and the AC Delco brake shoes has the same number as yours.  Rick D.

[elane352]

Okay Rick; I will get right on it. Thank you.

You might want to go back a few more years.  A '78 uses self adjusters.  Check your bore size and shoe width, drum diameter.  I went back to a '63 F100 w/223 cu in.  7/8 bore, 11 x 1.75 shoes, manual adjust, different part numbers left and right wheel cylinders.  I don't know what your measurements are  but I think you're on the right track.  Try a f250 if shoes don't match.

[Dave72dt]

Does the backing plate show any evidence of park brake provisions.  4 bolts or 5 to bolt backing plate to axle? Any casting or stamped numbers on the housing or carrier or a tag w/numbers?

[elane352]

Hello All,

 

I was able to put on the Ford 1978 F-100 wheel cylinders and brake shoes on both rear wheels from Rock Auto this morning. I did not have a problem with them fitting.

 

Dave, it was interesting that you mentioned parking brake provisions. I was looking for them since that is the type of set-up I have on my 64 C10. I saw nothing like that on the

D-100 and figured I needed to check my shop manual to see how the parking brake is set up. 

 

I have the 4 bolt backing plate to the axle which looks like the "Big Ford/Torino" style based on my research. 

 

I remember looking a few weeks ago for numbers on the housing or carrier. I did not see any, nor a tag number.

 

I have some new spare drums in the garage that look like they will fit. I will try them next weekend when I return to where the truck is.

 

Thanks again for the helpful information.

 

Edward
