Your file does not have adequate rights, the udev rules are not 
executable files and are owned by root:

# sudo chown root:root /etc/udev/rules.d/60-brother-libsane-type1.rules
# sudo chmod 0644 /etc/udev/rules.d/60-brother-libsane-type1.rules

These two commands will restore the rights of the file!

SYSFS{idVendor}=="04f9", GOTO="brother_mfp_udev_2"
ATTRS{idVendor}=="04f9", GOTO="brother_mfp_udev_2"

The two lines above verify that the usb device is a brother brand,
SYSFS does not exist or no longer exists as attributes, I suggest you 
delete the line. The work is done by the remaining line:

ATTRS{idVendor}=="04f9", GOTO="brother_mfp_udev_2"

# sudo udevadm control --reload-rules && udevadm trigger

This command allows you to reload udev rules without rebooting!
