The small triangle next to it is a piece that crumbled off when I removed the pad from the calliper.
It is a bendix pad and from the rear of a commodore.

Can someone explain to me how this pad has failed?

I'm only guessing here, but perhaps the pad flexed? It looks as though the end of the pad closest to the camera flexed, causing the pad material to crack and suffer a failure.
That or the pads were hot and you drove through some water? That would also stuff the rotors too. How are the rotors? What is the opposite pad like?
Cheers,
Clint

^ Rotors are ok. Opposite paired pad looks ok-ish... Opposite side (previous owner) was not changed at the same time and was worn out.

incorrect installation, maybe they have been used in an emergency and caused too much heat - thermal expantion - crack.

looks like someone pushed the piston back with a screwdriver against the pad
