Description
Description
Brake fluid tester for fast and reliable brake fluid testing
- ✔ Fast moisture measurement directly at the reservoir
- ✔ Easy-to-read LED display for immediate condition assessment
- ✔ Compact design for workshop, service and mobile use
- ✔ Suitable for DOT3, DOT4 and DOT5 brake fluids
- ✔ Rugged sensor electrodes for regular maintenance work
The brake fluid tester allows a quick check of the water content in brake fluids and supports workshops as well as home mechanics with safety-relevant vehicle maintenance. The integrated LED display makes it possible to assess the condition of the brake fluid within a few seconds.
The compact test device works by conductivity measurement and indicates different moisture levels directly via coloured LEDs. This makes it possible to detect at an early stage whether a brake fluid change is advisable or necessary.
Precise moisture control for everyday workshop use
Brake fluid absorbs moisture from the environment over time. Even an increased water content can significantly reduce the boiling point and negatively affect braking performance under heavy load.
The brake fluid tester measures the electrical conductivity of the fluid and assigns the measured value to a defined warning level. The coloured LEDs allow quick interpretation without additional measuring instruments.
LED display with clear condition assessment
- Green LED: water content below 1.5 %, brake fluid in good condition
- Yellow LED: water content between 1.5 % and 3 %, check recommended
- Red LED: water content above 3 %, brake fluid change advisable
- Flashing red LED: indication of a low battery level
Suitable for various brake fluid types
The test device supports checking DOT3, DOT4 and DOT5 brake fluids. This makes the tester suitable for many vehicles in both private and professional workshop use.
Compatibility depends on the brake fluid. Before use, you should check which type of brake fluid is used in the vehicle.
Compact test device for service and maintenance
Thanks to its handy design, the brake fluid tester is ideal for daily use in workshops, during vehicle acceptance or when inspecting used cars. The automatic switch-off reduces power consumption and keeps the device ready for use in everyday work.
The rugged measuring tip is designed for short-term contact with brake fluid. After use, we recommend cleaning the sensors in order to remove residues and to support consistently reliable measurements.

You can choose to pay by bank transfer (prepayment), PayPal (direct debit and credit card via PayPal), Klarna (purchase on account or installment payment), Shop Pay, Google Pay or cash on delivery. If cash on delivery is selected as the payment method, an additional fee of €9.99 will be charged.
Free shipping within Germany for orders over €50.
Shipping costs within the EU are €14.99. For orders over €100, shipping within the entire EU is free.
The delivery time within Germany is usually 1–3 business days.
Worldwide shipping – to countries outside the EU – is also available. The applicable shipping costs are calculated and displayed during checkout depending on the destination country. For deliveries to countries outside the EU, additional customs duties, import taxes or other charges may apply, which are to be borne by the customer.
Digital licences and unlocks
Update licences, Secure Gateway unlocks and HaynesPro access are digital content. No shipping costs apply – you receive the activation code by email once payment has been received, usually within 1–3 working days.
If the licence is tied to a device, enter your device serial number directly in the order form when purchasing. That way we can set up the activation for your device without having to ask.
Please note: with digital licences the right of withdrawal lapses as soon as we have begun supplying them and you have expressly agreed to this beforehand. For devices and all other goods the statutory right of withdrawal applies unchanged.

Frequently asked questions
At what water content should the brake fluid be changed?
At what water content should the brake fluid be changed?
The LED display assigns the reading directly to a level: green means less than 1.5% water content and the brake fluid is in good condition. Yellow stands for 1.5 to 3% and therefore a recommended check. With red the content is above 3% and a change is advisable.
Which brake fluids is the tester suitable for?
Which brake fluids is the tester suitable for?
The tester supports DOT3, DOT4 and DOT5. Which type is used in your vehicle is usually stated on the cap of the reservoir or in the manual. Check this before use, as the measurement depends on the brake fluid.
How does the measurement work?
How does the measurement work?
The device measures the electrical conductivity of the fluid. As the water content rises, this value changes, and the device assigns it to a fixed warning level. The measurement takes only a few seconds and is carried out directly at the reservoir.
Does the tester replace an inspection of the brake system?
Does the tester replace an inspection of the brake system?
No. The device only checks the moisture content of the brake fluid. It does not replace a full technical inspection of the brake system by qualified personnel. It is a testing device for condition checks, not a diagnostic device and not a vehicle scanner.
What does a flashing red LED mean?
What does a flashing red LED mean?
A flashing red LED indicates a low battery level of the tester, not the condition of the brake fluid. In that case, replace the AAA battery before continuing to measure.
