Clean brake fluid plays a vital role in internally lubricating brake components and allowing your vehicle to stop efficiently, especially under heavy loads or high temperatures. The average motorist drives 10 to 15,000 miles a year and will use their brakes about 75,000 times. Therefore, brake fluid should be tested regularly to ensure it remains effective, and should be changed as needed. Service recommendations can range from twelve months or twelve thousand miles to once every three years.
Brake fluid is ‘hygroscopic,’ and may absorb moisture through microscopic pores in the hoses and seals. Brake fluid saturated with water lowers the point at which the fluid may boil and may render your brakes ineffective. This can result in an accident. If this is left untreated, this moisture could also corrode many internal parts leading to costly repairs and replacement. At high temperatures, water vaporizes, turning to air in the brake lines.

From a safety standpoint, air in the braking system will dramatically increase the distance required for you to stop, possibly causing an accident endangering your life and those of others. From an environmental point of view there is very little impact unless internal corrosion causes a fluid leak.
