‘64 GMC 1000 rear brakes

[Claimchaser]

HELP !
I have a stock Dana rear end with leaf springs. I ordered all the parts for the rear brakes but they are not correct. My self adjusters are too short and the bar for the parking brake will not clear the backing plate.
What am I missing here ? I am at my wits end and every supplier swears they are sending what I need.

Did you by chance save the original parts for comparison……

Chaser:
GMC uses a Dana 44 which is different than a 64 Chevy. It's likely they are sending you Chevy parts assuming they are the same. Dana 44 's were used in a lot of Jeeps. You may have better results ordering your parts through 4x4 suppliers who are familiar with those differentials.

Hope that helps.

The only parts that were there were two brake shoes, the adjuster and three springs. The rest of the parking brake and self adjuster parts were missing.

I found one strut bar and the Self-Adjusting brake actuators.
I will PM you the numbers and links. They are hard to find and not cheap

[Claimchaser]

Thank you! I knew someone must have been through this as well. My luck to end up with something off the wall LOL

Here is a picture of my GMC Dana 44 rear brakes after I installed new parts.

For some reason, I don’t have enough tension to put the self adjuster to its proper position. like the yellow rod is too long or something. I’ll post a picture of what I started with and you will see what little I had to start with.I have already purchased two cross bars for the parking brake and neither are even close.I have had this truck for several months and this is all that is keeping it in the garage after sitting for 34 years,it runs great just need to get it outside to clean out the mouse crap and take out the tank to be flushed and the seat. You can’t safely take a breath inside the cab. I think I will chop on the ones I have since I can’t return them to Canada as they were reproduced for me when I purchased them.I am about ready to jerk the whole rear end out and swap it for something I can gets parts for.

Does the truck have a parking brake on the driveshaft? That would explain some of the missing parts. In that day, a lot of vehicles didn't have self-adjusting brakes, which could explain those parts missing. Looking forward to pics.

My push rods and crossbar are different, crossbar has to have an offset to clear the backing plate and the push rods are notched to fit around the brake shoes. My parking brake, which only had the under dash lever and brackets on the crossmember, has cables with two bolts into the backing plate not a hole the cable clips into. This must be a rare set up as very few people understand what I am trying to explain LOL, story of my life, I always end up with the oddball stuff.
Thanks for all the help for sure!

What are “My push rods”? list the group number in the PDF.
The cables have two part numbers. 2457046 81” and an Interchange Part Number: 2444402 82”. EBay has them, they are listed as 1965 Chevrolet Ser.10 1/2 T Truck w/ Leaf Springs .

[Claimchaser]

Push rods are inserted on each side of the wheel
brake cylinders.

The yellow rod should be 5 11/16 O.L.
You have the wrong brake Adjusting Actuator Levers.
Look at the adjuster in the PDF and look at the pictures.
The gmc part numbers are 5464208 and 5464209.

1965-1966 chevy 10 with leaf spring 5464917 stamp 5464208 L , 5464918 stamp 5464209 R

Oldsmobile 5464697 and 5464698 stamp 5464208 and 5464209.

[Claimchaser]

This is all I started with.So far I have found a kit of both left and right adjusters for $69.00. Crazy money lol Going to keep looking.

[gmc jr van]

Talk about Crazy money. I hope you have the correct Parking Brake Actuating Levers. I found the left and right for $145 each.
