where are you planning to mount the brake servo? If you use those wont it be in the way?

I am planning to make a CF top plate for the center dif mount and extent it to the back and then mount a mini servo on it. The Hitech CRT.5 steering servo has 80oz of torque which should be enough. It think it will work fine and keep everything up adn out of the way for mounting the battery and ESC to the chassis.
