Instructions for Use:

🔍 The brake fluid detection pen utilizes conductivity changes to determine moisture levels in brake fluid. Different LED colors provide clear information on fluid status— a high moisture content lowers the boiling point, affecting brake performance. A red LED signifies that the fluid requires immediate replacement, while green means it is in good condition, and yellow suggests that replacement will soon be necessary.

LED Indicator Display:

🟢 1. Green LED: Water content in brake fluid is below 1.5%, indicating the fluid is in excellent condition.

🟡 2. Yellow LED: Water content is between 1.5% and 3%. The brake fluid is still usable, but a retest is advised in six months.

🔴 3. Red LED: Water content exceeds 3%, necessitating an immediate brake fluid change.

🔴 4. Red Flashing LED: Indicates that the battery needs replacement.

Technical Parameters:

🟢 Green: Battery and brake fluid condition is good.

🏆 Green/Yellow: Water content is less than 1%. The brake fluid maintains optimal performance.

🧩 Green/Yellow/Yellow: Water content is about 2%. The fluid can continue to be used safely.

🔴 Green/Yellow/Yellow/Red: Water content is about 3%. A fluid replacement is recommended.

🧩 Green/Yellow/Yellow/Red/Red: Water content is 4% or more. The brake fluid urgently needs replacement for safety.

Packaging Includes:

🧩 A high-quality brake fluid tester pen designed to ensure the safety and reliability of your vehicle's braking system.
