You might try and load the drivers provided by Brother directly.
The following page has printer, scanner, fax, and fax modem drivers.

You can try the Driver Install Tool to install the drivers, but I have a
Brother HL-2275DW printer and I didn't get very good results with it. 
Eventually, I just manually installed the Generic CUPSwrapper and Generic 
LPR driver packages and then manually set up the printer through the 
Ubuntu's printer setup dialog. I did notice that the tool is at a much 
newer version that what I used, so they may have fixed the bugs that I 
ran into.

For the scanner drivers, you obviously want the one matching your 
machine architecture and the scanner settings package. The udev rules 
provided by the libsane package doesn't contain any entries for Brother 
scanners, so your scanner device probably doesn't get the proper 
permissions and ownership setup up when it's detected. Brother's scanner 
settings package will install a udev rule for your device that should set 
ownership and perms up correctly.

You may also have to add your username to the "scanner" group if it still 
has a problem with permissions.
