Brother doesn't list a driver for this scanner. Is there one somewhere else?

In this case, Brother provide a Linux driver for this on their website in RPM and Debian variants for 32-bit and 64-bit:

They also provide installation instructions for Linux:

That said, Linux itself contains support for thousands of hardware products built-in, often even when the hardware vendor doesn't (for example, sometimes open source developers will have written their own alternative driver).
I would encourage you to see if you can use it without installing the hardware vendor's driver first, just to see if a built-in driver in Linux will handle it. If so, that'll be a cleaner solution for you.
Often, the drivers supplied in Linux will be open-source and maintained while drivers supplied by manufacturers may be closed-source and dated. That said, often there is no existing open-source driver for a piece of hardware. And sometimes the manufacturer themselves made their driver open-source and so a derivative of that appears in Linux.
You can download the driver from:
If you are running 32bit: here
If you are running 64bit: here
Press I Accept
and wait to finish download.
Now to install the driver:
cd ~/Downloads
sudo dpkg -i brscan*.deb
Install the udev rule setup.
If you need to debug, then run:
