Schwaben Pocket Brake Fluid Tester

It is necessary to check the moisture content of your brake flluid beacuse brake fluid is hygroscopic, meaning it readily absorbs moisture. Over a period of time moisture will cause brake fluid to degrade. Once brake fluid reaches a certain level the brake fluid is no longer able to function properly in the brake hydraulic systems.

This Schwaben Brake fluid tester has a green, yellow and red light that represents moisture content of DOT 4 brake fluid to determine if service is needed.
