Introduction
The TESMEN TBF-300 Brake Fluid Tester is a diagnostic tool designed to assess the quality and condition of brake fluid in vehicles. It accurately measures the water content in brake fluid, which is crucial for determining if the fluid needs replacement. Over time, brake fluid can absorb moisture from the air, leading to reduced effectiveness and potential compromise of braking performance. Regular testing with the TBF-300 helps maintain optimal brake system safety and longevity.
The TESMEN TBF-300 is suitable for use in various automotive environments, ensuring brake fluid quality in diverse conditions.

Operating Instructions
Follow these steps to accurately test your vehicle's brake fluid:
- Step 1: Power On
Long press the power button to turn on the device. The display will illuminate. - Step 2: Select Brake Fluid Type
Press the "F" button to cycle through and select the appropriate brake fluid type (DOT3, DOT4, or DOT5.1) for your vehicle. Ensure the selected type matches the fluid in your vehicle's reservoir. - Step 3: Insert Probe
Carefully insert the tester's metal probe into the brake fluid reservoir. Ensure the probe tip is fully submerged in the fluid. - Step 4: Read Data
The device will automatically begin testing. Read the moisture content percentage displayed on the screen. The backlight color will indicate the fluid's condition.
To hold the current data on the screen, short press the data hold button (often labeled "H" or "M/C"). Press again to release.
Understanding Readings and Alarms
The TESMEN TBF-300 provides clear visual indicators through its backlight system to help you interpret the brake fluid's condition:
- Green Backlight (0%~2%): Indicates that the brake fluid is in good condition and has minimal moisture content.
- Yellow Backlight (2%~3%): Suggests that the brake fluid has absorbed some moisture and should be monitored. Replacement may be necessary soon.
- Red Backlight (More than 3%): Signifies that the brake fluid has a high moisture content and requires immediate replacement to ensure braking system safety. An audible alarm will also sound.
It is important to replace brake fluid when the moisture content is high, as excessive water can lower the fluid's boiling point, leading to brake fade and reduced braking efficiency.
Maintenance
To ensure the longevity and accuracy of your TESMEN TBF-300 Brake Fluid Tester, follow these maintenance guidelines:
- Cleaning the Probe: After each use, thoroughly wipe the metal probe with a clean, dry cloth to remove any brake fluid residue. This prevents corrosion and ensures accurate future readings.
- Storage: Store the tester in its provided hold-all bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears to ensure consistent performance. If storing for extended periods, remove the batteries to prevent leakage.
- Avoid Contamination: Do not expose the tester to excessive dust, dirt, or other liquids besides brake fluid during testing.
Troubleshooting
If you encounter issues with your TESMEN TBF-300, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or dead batteries; incorrect battery installation. | Replace batteries with new 1.5V AAA batteries. Ensure correct polarity. |
| Inaccurate or inconsistent readings. | Probe not fully submerged; probe tip is dirty; incorrect fluid type selected. | Ensure probe is fully submerged. Clean probe tip thoroughly. Verify correct DOT type is selected. |
| Display is dim or flickering. | Low battery. | Replace batteries. |
| No audible alarm when moisture is high. | Fluid moisture content is below 3%. | The alarm only activates when moisture content exceeds 3%. |
If the problem persists after attempting these solutions, please contact TESMEN customer support for further assistance.
