I remember your earlier post (or one very similar). Yes, it's common for front and rear brake reach to be different, though it's more common for the front to be shorter.
As for what to do about it, that's one of those "raise the bridge, or lower the water questions". One or the other is necessary, and either is fine. Usually, I'd expect to change the brake before the fork, but there might be reasons to do the opposite.
