brake help fast

[taylorhannum]

I Have a 1971 c20 pickup truck 2wd. It has a dana axle but I am not sure what size rear drums and shoes I need and I don't have to time take it all apart and look. I was hoping someone might be able to help me out on this. Thanks!

There are two sizes of rear shoes, depending on whether you have leaf or coil springs.
For coil you should have 11 5/32 X 2 3/4" Napa part # UP248R
For leaf you should have 12 X 2/12", Napa part # UP419R

Are you sure you need drums without taking it apart?

I have a C20 with coil springs and my drums cleaned up with very little metal removal. It's not easy to find a shop that can do this. An automotive drum lathe won't do it and a shop that does big trucks will tell you the drum is too small for their equipment.

I found a shop in Houston that does equipment like forklifts. Both drums $130.

Im sure I will need the drums. The brakes have been bad for a long time but i just never drive it. I figured it would be good to get new ones anyway because I can get drums and shoes for for 150 total here

The drums are the same size as the shoes. I doubt that you will need drums, unless the shoes have been metal to metal for awhile, they will be able to be resurfaced. Most automotive shop's lathes will be able to resurface a 12" drum.

That wasn't what I found. The problem was the hub. This is a C20.

Does anyone know where I can get a diagram or video online of how to remove the drum for this truck?
