Thank You for Your time Hans, I do not like 0777 as well, but I was shooting in the dark. As stated, I tried
## Brother MFC-1910W
ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="035d", MODE="0666", GROUP="scanner", ENV{libsane_matched}="yes" (or 0660 0664 0777 modes)
which should be the equivalent of Your
# Brother brscan3 devices
ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="*", MODE="0664", GROUP="scanner", ENV{libsane_matched}="yes"
