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

1 The green LED lights = 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%, continue to use, test again six months later.
3 The red LED lights = water content in the brake fluid H2O > 3%, can not continue use brake fluid needs replaced.
4 LED red flashing: battery replacement.
5 LED yellow: low moisture content, check again in six months.
6 LED green: brake fluid lines / cell row.

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.

Frequently Asked Questions

Which types of brake fluid can this tester diagnose?

This tester is designed to test DOT 3, DOT 4, and DOT 5 brake fluids.

What batteries does the device use and are they included?

The tester runs on 2 LR44 batteries. Please note that the batteries are not included in the package.

When should I immediately replace the brake fluid?

If the red LEDs light up, it indicates that the water content in the brake fluid has exceeded 3%. At this level, the fluid must be replaced immediately for your safety.

What does a flashing red LED indicate?

A flashing red LED indicates that the batteries are low and need to be replaced.

Does the tester have an auto-power off function?

Yes, it features an automatic shutdown function to save battery power when not in use.

How does moisture affect my vehicle's braking performance?

High moisture content in the brake fluid lowers its boiling point. This can lead to vapor lock, which significantly reduces overall braking efficiency and performance.
