About Brake Fluids

Brake fluid in the typical vehicle can become dirty in two years or less. This is due to the fluid absorbs moisture, which works its way through the hydraulic system. 

If you are driving in heavy braking conditions or hilly driving or when towing a trailer, moisture in the overheated in mountainous or hilly driving or when towing a trailer, moisture in the overheated fluid vaporizes and braking efficiency is reduced.

Sometimes even under normal driving conditions this happens, if the brake fluid is seriously contaminated. Not only is the fluid vulnerable to vaporizing, it also can freeze.

Brake fluid should maintain a sable viscosity throughout its operating temperature range. If it’s too thin or too thick, braking action is harmed. Beyond the vaporization hazard, moisture creates an extra dilemma for owners of vehicles equipped with anti-lock braking (ABS) systems. Rusted and corroded ABS components are very expensive to replace.
