## Description

Why do you need it ? As everyone who has cars know, people always spend hundreds of dollars in their vehicles to check the brake fluid or replacement. However, you don’t know you could save a lot of money by using this Brake Fluid Tester. This Brake Fluid Tester could check the health status of your car brake fluid, and tell you the percentage of water in brake fluid in the form of five LED indicators. Besides, through our brake fluid tester pen, you can know if it is necessary to be sent to workshop. All in all, the portable diagnostic testing tool not only would save you much time and money but also use easiest in you own hand. It’s a great choice if you want to drive safely without brake fluid problem. Why choose us? The shell of the brake fluid tester produced by our company is made of nylon material. Compared with the shell made of ABS on the market, the shell of our product can be anti-corrosion, because the brake oil is highly corrosive. Nylon material can resist corrosion, if it is an ABS shell, when the plastic part close to the test probe touches the brake oil during actual use. The surface of shell will be corroded and dissolved by the brake oil. Over time, the shell will be smash, which does not meet the export quality standard. How to use ? Open the hood of your car and find the brake fluid tank. Unscrew the brake fluid reservoir and pull off the cover of the brake fluid tester. Press the button to turn on the tester, and the green LED light will turn on. Insert the tester into the reservoir for seconds and the tester result will be correctly indicated by the LEDs light. Understand the status of brake fluid according to the results. the menu of brake fluid tester Package includes: 1pc x Brake Fluid tester(Battery Not Included)
