Technical parameters:
Green
: Battery OK, that is, brake fluid does not contain water
Green / yellow
: brake oil in water content of less than 1%, better brake fluid performance, ease of use.
Green / yellow / yellow
: brake oil in water content of about 2%, brake fluid can continue to use.
Green / yellow / yellow
/ red: brake oil in water content of about 3%, the proposed replacement of brake fluid.
Green / yellow / yellow / red / red
: brake oil in water content of at least 4%, the brake fluid must be replaced immediately responsible for very dangerous.
