Instructions:

Brake fluid detection pen is based on the change in conductivity to determine the moisture change brake fluid. It shows??clearly the extent of moisture contained by the light-emitting diode, high moisture content will lead to lower boiling point,? ?affect braking performance.

1. How Dangerous of a bad quality Brake Fluid? ?

1) The inferior brake fluid causes the brake failure easily,thereby lead to a accident
2) The Brake fluid is related to the life of Brade pads, if doesn't take it seriously, the life of brake pads is worried.

3% light indicates that moisture content of brake oil less than 3% , proposed to replace brake fluid.
4% light indicates that moisture content of brake oil less than 4%, brake fluid should be replaced immediately.

>Red LED: change brake fluid<

Functions:

1.check the car brake oil quality
2.5 LED lights display the percentage of moisture content in brake fluid,how the test results more accurate
3.Press the button for power on, green LED will light up.
4.Insert the tester into reservoir for a second , then the results will be indicated correctly by LEDs.
5.Testing for DOT 3, DOT4, DOT5 brake fluid
