This brake fluid moisture detection tool works based on a change in conductivity to determine the moisture level in the brake fluid.


It indicates the extent of moisture contained in the fluid by the light-emitting diode, high moisture content will lead to lower boiling point, affect braking performance.


Red indicates the brake fluid needs immediate replacement, green represents good condition, yellow indicates the state is acceptable but soon replaced.


The green LED light= Water content in the brake fluid H2O <1.5%, brake fluid qualified.


2 The yellow LED light = Brake fluid water content H2O = 1.5% to 3%, can continue to use, test again six months later.


The red LED light= Water content in the brake fluid H2O> 3% + Recommended not to continue to use the vehicle. The brake fluid needs to be replaced asap.
