That's odd. When I took posession of my Overlander, two springs on two wheels were broken. There was no shrapnel damage nor any loose pieces of springs floating around. The adjusters were right where they were supposed to be.

IMO, if a spring breaks, accelerated brake wear can occur (which is, of course, not a good thing). Nothing else, though, will happen unless the brakes are criminally out of adjustment.

i'm gonna jump in here, missed most of this thread since i was away deer hunting.

replacing the whole backing plate assembly is the safest and least expensive way to go. around here you cannot buy just the magnets for the cost of brand new dexter backing plates with new everything including the nuts and bolts!

ususally i get them from pioneer wheel and they are 50 dollars each. no headaches, just new parts.

The adjuster springs sole job is to hold the adjuster in place.

If the spring breaks, the adjuster will eventually fall out.

I agree IF the brakes are not adjusted every 3000 to 6000 miles.

My point is that it is not an immediate reaction.

There is more than one spring. Andy's scenario is a worst-case, if the spring that holds the bottom of the shoes against the adjuster break, and cause the damage he describes. If the other spring breaks, usually you will wind up with dragging brakes, which you may not notice until you notice the brakes grinding. Another thing I have seen, especially on trailers with brakes that are used occasionally, is the epoxy that holds the friction material will completely delaminate from the base, also known as the table. When this happens, the friction material will ride up over the friction material of the other shoe, causing the wheel to lock. That is another good reason to just replace the whole thing, even if the shoes have a lot of friction material left, the epoxy does have a finite life.

I've been into cars a long time, I disagree, it primary job it to keep the adjusting wheel from turning freely not keep it in place that is done by notches in the shoe plate.

As far as replacing the whole thing that is not common on cars, they are always rebuilt.

If you check your wheels every 10K you should be in good shape. To have the other possible failures mentioned may only happen if you ignore the brakes for a very long time

Ok ,the spring does hold the adjuster star wheel piece from turning ,but if the
spring breaks ,the adjuster does fall out absolutely .It did on my 60 when i first purchased it .going along i heard a squeal from the wheel ,pulled over
in a good spot and proceced to pull the wheel and drum .found the adjuster
in the drum and broken spring for it ,it does not stay in place by itself ,must
have the spring in place ,dual purpouse ,not one or the other .further, the
spring on most all Bendix or other drum brake setups that are self adjusting
(our brakes on the trailers are not) do use the spring to hold the adjustment ,it holds the self adjuster lever tight against the star wheel adjuster so it cannot turn but with the lever and cable mechanism that
actuates it . Any time that spring breaks parts do fall out .The reason for
complete backing plate replacement is for the ease of replacement and repair
and cost effectiveness .If you pull apart your brakes and its all great,but a worn magnet only ,Id replace the magnet only .Most of the time ,it needs
shoes ,or grease contamination and all ,then Id replace the whole backing plate ,its the best way to get a complete job with all new parts .Id go for
peace of mind and a quality job always .

I think the adjusters on the older brakes had a shorter notch so it was easier for the works to fall out if the spring broke.

It didn't on my '67. Perhaps a picture would help. As everyone knows, properly adjusted brakes drag ever so slightly on the drums. Study the adjuster with respect to how the shoes rest against it.

The adjuster can not immediately fall out on an original 1967 backing plate when the spring breaks if the brakes have any modicum of adjustment.

Here's pictures of the old brakes with the shorter adjuster, and the new Dexter brakes with the longer adjuster.

The earlier brakes shoes also appear to have less toe, so if the spring breaks it has less of an overhang to hold the adjuster from falling out.
