2001 3500 - Drum brake rebuild-horseshoe washer?

[DownByTheRiver]

Where in the world does the c/horseshoe washer go? Two came in my parts kit, but none came off the truck, and I can't find any parts diagram or section in the fsm that mentions it. I don't want to just leave it off, but I can't find where it goes for the life of me.

Sometimes the adjusters have something like this from what I remember. Does it go between the shoe and the adjuster or something?

I have removed them from the emergency brake cable mount. The last one I did recently on my hhr came with the emergency brake cable bracket and no horseshoe clamp. They clamp around a pin like a circlip does

Just a side note in case you didnt already know... When you install shoes on a drum brake system you need to match the new shoe to the inner wall of the drum. This means sanding down the new shoes high spots with sand paper to match the curvature of the drum. Otherwise what will happen is the shoe wont fully touch and result in soft spongy pedal and weak brakes.

It's been awhile but I believe it goes on the end of pin 17 on the inside of the shoe.

Thank you sir, this has to be it. I noticed the top of the shoes were not parallel with the backing plate last night (canted inboard) and was coming back this morning to ask.

Well took another look tonight after I replaced my hydroboost. Doesn't really look like there's a spot for it on pin 17 but behind the shoes. Still a little stumped.

Another thing is my shoes lean in at the top. I figured that washer would go behind and take up some of the lean. Guess not? Haven't done drums since my 68 c10, so forgive the ignorance here.

If the shoe to backing plate perches/mounds are grooved or excessively worn this can cause what your pictures show. Lay your new shoes on a known flat metal surface and make sure they're flat = in the areas where the metal portion of the shoe will contact the backing plate perch. Then without installing shoe to plate place the shoe where it would go in normally installed position and check if the metal portions of the shoe "correctly and fully" contact the perches. If there are deep grooves and low spots on the perches you'll need to flatten them and make sure shoes completely contact all perches. I've had some so bad I had to weld material on and smooth out. Tip: when installing new shoes use a little anti-seize on the perches to aide proper return/application. Also, make sure self-adjuster star-wheel threads are clean and lubed. Also: DITTO on what KATOMB said = fit the shoe material to the drums "even" if they're new or cut/trued up.

In my younger days I would have the drums turned and the shoes "ARCHED" of "ARCED" ??? to match the surface of the drum by the old school NAPA shop.
