shit, I deal w/ the drums on my truck about once every other year...
and last summer was the last time I fooled with them. I do distinctly
remember however that the short shoe on my truck had the longer
friction on it.
The steel frame work of the shoes are the same front side (primary) and back
side (secondary) of the drum. The length of the friction material is what
makes it a short or long shoe. That's the difference in them.
You can't have a short shoe with a long friction.
If you are saying (as I think you are) that the front shoe on your
truck had the longer friction material....then you need to pull
your rear brakes apart and put the long shoe to the rear side.
There are three catagories that I've seen. Long shoe, short shoe..
always the short shoe to the front.....same length material, "primary"
and "secondary" printed on the metal frame to indicate which shoe
is the front (primary).....and then same length material and it doesn't
matter, either shoe can be the front or rear.
I'm saying that on my brakes (which my uncle, a mechanic of 30+ years
exp. installed) the shoes only went on one way and I *think* the shoe
that was physically shorter had the longer friction on it. however,
I'm not pulling anything apart as my brakes work just fine (i.e. no
wet weather grabbiness, tons of stopping power, etc.)
the brakes are the 11 5/32" X 2 1/2" drums used in LD 2500's the shoes
were the mid level Albany's from AZ.
Yeah, I'd agree. I've never run into GM
brake shoes that have different size frames.
It's always the lining that can differ in size,
not the actual shoe.
Unless it's some one-off that I haven't
run across...always possible.
