Applying the brakes earlier will always give you less wear, because if you do this you're dissipating the energy anyway through rolling resisistance and drag - you haven't got you're foot on the accelerator.
If you really wanted to you wouldn't have to use the brakes at all , just let it coast to a stop, then you would have zero brake wear.
You wouldn't do this in practice but it does demonstrate that braking earlier will always give you less wear.
It would be different if you were in a vaccuum and ignored rolling resistance/ bearing friction etc.
