Einfach zu bedienen...übersichtliches Display. Durchdacht ist die biegsame und vom Stammgerät weiter entfernt angebrachte Sensoreneinheit gerade im Umgang mit Bremsflüssigkeitsbehältern.

Nice display and loud audible notification. I’ve never had the need for a device like this. But since I’ve decided to do some of my own 4Runner maintenance, this was on my list of things to buy to take the guess work out the brake fluid management. It indicated I was ok, so I don’t need to bleed the brakes just yet. I did test it with just water and it was off the charts. I didn’t have fresh brake fluid to test, but I know old the existing fluid was and it confirmed my suspicion. Saved me time and money. I’ll test on the next oil change which I intend to do myself. There are some great how to on you tube. For Toyota vehicles look up the car care nut on YouTube. When finished, I took the batteries out, cleaned and dried the probe, placed in the box for the next use, about 1 year from now. Take care out there and be safe.

I tested it on an old brake fluid oil. It quickly gave me a reading. I like the flexible probe. Ideally I should compare it with a different tester to make sure the ready is truly accurate.

Brake fluid is hygroscopic, it absorbs moisture from the air. That is bad, the moisture can lead to corrosion of expensive braking components and potentially brake failure...not a good thing.This device simply measures the moisture content of your brake fluid. Just dip the sensors in your fluid and wait for the results. Green- 0-2%, you're good. Yellow-2-3%, start buying brake fluid. Red-3+% change it.If your car is under warranty, absolutely follow the manufacturer's specifications as to flushing your brake fluid. If this tester indicates you should change your brake fluid before then, by all means do it. After your warranty has expired, however, only change your brake fluid when you need to, not when the mechanic doing a "safety check" of your vehicle says.

Ce testeur est très bien fait, bonne qualité de fabrication, le fait d'avoir les électrodes de mesure bien séparées de l'appareil est très pratique pour les plonger dans le vase d'expansion de liquide de frein (quand c'est possible).Mesure bien lisible, on sélectionne le type de liquide, dot 4, 5.1... Et on obtient le pourcentage d'humidité dans son liquide. C'est vraiment un plus d'avoir cet outil, car la périodicité de changement de liquide de frein est parfois arbitraire, on préconise 2 ans, mais par exemple au bout de 2 ans je n'ai qu'un pourcent d'humidité, ce qui est encore tout à fait acceptable.Bon appareil que vous recommande.

I own two older vehicles and have never changed the brake fluid in either one. I ordered this brake fluid tester to check whether or not the fluid should be changed. Surprisingly, the brake fluid in each vehicle read low levels of moisture (indicating that I do not need to change the fluid in either vehicle). I put water in a container and tested the meter. The meter read extremely high levels of moisture in the water cup. I am unable to tell how accurate the brake fluid moisture reading was, but I do know that it does water moisture levels.

I have a 2017 Silverado that bought new exactly 7 years ago. The manual says to replace fluid every 5 years so I’m a little behind on this. I opened up my brake fluid reservoir and tested my fluid. It tested at 1.5. I had two quart bottles of unopened Lucas Dot 3 on the shelf, and I was concerned that maybe they had been sitting there for too long. I tested both of them and they both got 1.7. I didn’t want to put something with a worse reading in, so I went and bought a new bottle of Prestone from AutoZone. It tested worst of all at 2.2. I can’t imagine that three unopened bottles tested worse than 7 year old fluid in my truck. What a waste of time.

Routine maintenance is a funny thing. Your driving in your climate vastly could differ from my driving in a different climate. Out west where it is very dry, and you spend your driving mostly on vast open stretches of road? You probably won't burn up the fluid from hard stops, heat build-up, contaminated and humid air.But you live in a humid place and drive in the city? Your fluid is going to need to be changed a lot sooner.Bleeding brakes isn't fun. You usually need two people, and sometimes some expensive tools. To bleed ABS, you often need a professional level scan tool. What I'm getting at here, is, it's not cheap to do. Places that do it for you know that and are glad to charge you a lot for it. If you happen to have a vehicle with a brake fluid warning, and it is a type where the warning is done simply by miles or time, then there is a decent chance the fluid may be past its prime, or possibly completely fine.Use this and save yourself some money. Perhaps at every oil change, or once a month, pop off your fluid fill cap and test it real quick. If the fluid is getting worn out, replace. If not, let it ride.Cheap tool, saves you potentially thousands in costs associated with either running overly hydrated fluid rusting out lines, or wasted money changing perfectly good fluid.

I was looking for a way to check brake fluid without using up my Phoenix Systems test strips prematurely. Even though they test for two different things (the pen tester checks moisture levels and the strips check for copper levels), I was hoping that the results would show around the same scale range for each of their respective tests (ie, change soon, change now, etc...).I tested the brake fluid with this pen tester and the results were 2.5% (3%+ is change now). I then tested the fluid with the Phoenix test strips and the results read 100 (200+ is change now). To me, that correlates pretty well to each other. So now when I test fluid, I can pull out the tester and check the results before wasting my test strips. If the reading is 2.5% or below, there's no need to waste a test strip. If the readings is higher, then I can test with a strip to confirm it's time to change the fluid.

I too question the accuracy of this pen device, but also don't have one that's calibrated to compare it to. It does however give me a number to put on things, to give fluid a relative measurement to other vehicles I own.
