water content in the brake fluid H2O <1.5%, brake fluid qualified
2. the yellow LED lights
brake fluid water content H2O = 1.5% to 3%, can continue to use, test again six months later
3. the red LED lights
water content in the brake fluid H2O> 3%, can not continue to use the brake fluid needs to be replaced Red LED: change brake fluid
