I'm sure there are many more requirements than viscosity. Lubricity, bulk modulus, and boiling point are the first things that pop into mind.

The hydraulics in a brake system only need to transmit and multiply the input force applied at the brake pedal. In addition, the fluid needs to withstand high and low temperatures (not freeze or boil), not corrode the brakes, brake lines, or any soft components of the system, not absorb water, etc. Having a high viscosity doesn't necessarily indicate a superior brake fluid, and would probably be unusable in cold temperatures.
