Drum brake diagram

[Ratpin]

Can someone please link me to a PDF for a front drum brake assembly diagram for 1/2 ton task force trucks? I have the service manual for my 1959 apache but nowhere in the book does it show a blow up of the front drum brake internals and I am ready to reassemble my front brakes. I would like to have a visual reference to compare against. Thanks!

This isn't a diagram but is the photo of a left front backing plate with shoes and springs installed that I jacked off Ebay. It may be sideways as the photo on Ebay was sideways and Photobucket is giving me a hard time today.

Things to note:

The shoe with the least lining always goes on the FRONT side. Meaning that the shoe with the most lining goes to the rear on both sides of the truck.

The star wheel on the adjuster goes over the slot in the backing plate on both sides. Also free the adjusters up and put a little bit of lube or antiseize on the threads before putting them back together. I usually screw them in and after having the shoes on and all the springs in place adjust them out so the drum just slips over the shoes so I don't have to spend a lot of time cranking on the star wheel with the brake spoon to get them out and tight.
I was taught to adjust them out so the wheel would not turn and then back them off 11 clicks so you had a bit of drag between the shoes and drum. That has worked well for me for the past 50 years.

Remember no greasy finger prints on the lining or the inside face of the drums.

Pack the bearings correctly with a good grade of wheel bearing grease before assembly.

I might have a better diagram in one of my books but will have to loo.

I photo mine and work on one side using the other for reference. Also a freak about making my own disassembly sketches and notes. Comes in handy when it takes 15 years to put it back together.

When I was doing brake jobs daily and some times several a day I would drop all four drums and while turning the first drum do the brakes on one wheel and work my way around. That way I had the opposite side for reference.

I learned that by taking every thing off a car that was a bit different than what I was used to and then having to spend an extra hour figuring out how it went back together long before the internet was a reality and computers took a space the size of a one car garage to house them.
