Some manufacturers may not include it in their maintenance schedules and others do. Some vehicle this maintenance is built-in the system that it will remind you when it is time to be service.
Brake fluid is hygroscopic, which means it absorbs moisture. Brake fluid in a sealed container can last years, but moisture from the outside air can work its way in through the brake system. Moisture in the brake fluid can cause internal corrosion in the brake lines, the wheel cylinders, the calipers and the master cylinder along other brake components. In addition, moisture in the brake fluid lowers the boiling point of the fluid, diminishing the ability to stop in panic stops as heat in the system will increase. Replacing brake fluid is less expensive than replacing brake lines, calipers, wheel cylinders, or a master cylinder that has failed due to being corroded.
Follow the manufacturer’s recommended service interval. I would recommend every four or five years and have it done at the same time as other brake service is being done, such as brake pad/shoe replacement.
