From the Mini Owners Manual:
Brake fluid is hygroscopic, that is, it absorbs moisture from the air over time. In order to ensure the brake system's safety and reliability, change the brake fluid every two years. Brake fluid is toxic and also damages vehicle paintwork. Always store brake fluid in tightly-closed original containers kept well away from the reach of children. Do not spill the brake fluid and do not fill the brake fluid reservoir beyond the MAX mark. The brake fluid could ignite upon contact with hot engine
