Brake fluid is a hygroscopic liquid, which means that it gradually absorbs water from the atmosphere. This process causes the boiling point of the brake fluid to reduce and this can result in the brake fluid boiling and turning to a gas under prolonged heavy braking (know as a vapor lock).
Once the brake fluid becomes saturated with water the pressure of braking can cause the moisture to be forced out of the brake fluid, this moisture can speed up internal corrosion of the brake cylinders eventually causing them to seize up.
Most vehicle and brake fluid manufacturers recommend that the fluid should be completely changed every 2 years regardless of how many miles a vehicle uses. Failure to do in in a new car risks voiding the car's warranty.
The two year limit if fairly conservative as it is based on a worst case scenario of the fluid being exposed to very high humidity all the time. As an alternative to regular two yearly fluid changes a sample of the fluid can be taken every 6 months (after the first 2 years) and its boiling point tested, once the boiling point falls below that specified by the fluid manufacturer the fluid must be changed. This process will usually allow you to increase the interval between changes, however few service centers have the necessary equipment and expertise to carry out this test properly

Do you need to replace the brake fluid on a 2006 Toyota Sienna?
The best answer is to ask your local Toyota dealer. The alternative answer would be to screw the cap off your tank in the engine bay that says brake fluid. The fluid on the stick should be a clear light brown. When you touch it the fluid should not be slippery, greasy, or discolored. If there is any sediment in there then change it right away and make sure to clean out the fluid reservoir. Also change your brake fluid every two years and flush out the brake lines for superior maintenance.

If Prius 2007 need a brake fluid change when should it be done and how often?
If, as you say, it needs doing then it should be done as soon as possible. Brake fluid seldom needs changing though it does degenerate over time, mainly by absorbing moisture. The precise detail will be in your manual. The fluid reservoir needs checking topping up occasionally and certainly will require it after a brake pad change.
