That's known as the brake "lining", and is usually bonded securely to
the metal frame, and together make up the "shoe". With age and use, they
can start to crack and come apart, sometimes just losing chunks,
sometimes coming completely unglued from the metal part.
If you have disc brakes on the rear (calipers and pads on the outside),
and just the parking (not emergency) brake shoes on the inside, then you
only need to worry if you rely on your parkng brake to keep the truck
from moving unexpectedly (parking on really steep hills, or with a
manual transmission, pretty much any hill). If you only lost a small
chunk, don't worry about it. But if you lost the whole lining off a shoe....

Just don't use your parking brake and everything will be fine. Remember to
park on level surfaces. Take a carpenter's level with you so you can check.
I would change those shoes if you like to use that mechanical linkage brak
