Product Description

The car brake fluid quality can be tested quickly to see if it's qualified, which will remind you to change the brake fluid when necessary so that you don't get into a traffic accident.
With 3 colors green, yellow, and red, the LED indicators show the amount of water in the brake fluid.
This calibration is for cars using DOT4 or DOT3 brake fluids. (DOT3 is almost completely replaced by DOT4 due to its better performance.)
The results are displayed within seconds, and the system is very
This item has been tested for CE and RoHS compliance. The helmet is equipped with a protective cap. It takes one AAA battery. An optional 5V battery is included (not included).

Questions & Answers

Another type of tester is specifically calibrated for dots 3, 4, and 5. The tester tests all three in the same way, how is that done?

For DOT3, DOT4, and DOT5 auto brake calibration

Do we have the ability to test valvoline dot 3 and 4 synthetic brake fluid with this tester?

That is true, the main difference between the two fluids is the boiling point. The one I have I use to test both racing spec fluids as well as common fluids

What is the accuracy of dot 3 calibration?

In short, yes.

Does that mean all versions of dots3,4,5 will work? This isn't specific to Dot 3 or 4 or 5, but some of it is. ?

You can use it for dots 3, 4, and 5. There are no problems with any of them.

Selected User Reviews For Fuzbaxy 2 Pack Brake Fluid Tester Automotive Tools Diagnostic Testing Tool Auto Brakes Calibrated for DOT3 DOT4 DOT5 with 5 LED Indicator

It can be used to test the moisture content of brake fluid in automobiles
5/5

I think it's a good method One of my older vehicles had a lit red LED in the place where fluid passed OK in my newer vehicle. In testing the fluid with test strips (that detect copper), I saw that the fluid on my older vehicle was still operable, however test strips detect breakdown and corrosion. There is a very good chance moisture in the system will cause corrosion, so this tester warns you to change the fluid before the test strips fail. The only advantage of test strips is you can show the customer the results, but I suppose you could always show him the indicators on the tester. It is not only possible for moisture to cause corrosion in brake systems, but it also lowers the boiling point of brake fluid, which could cause catastrophic results should the fluid heat up and boil, causing a very spongy or even loss of pedal height as a result.

Don't do it
3/5

I don't even know how I feel. In all honesty, I only do reviews when they are very good or very The situation is extremely serious in this case. As a brake fluid user I use DOT 3. My lights would expand the deeper I dipped it, so the longer I dipped, the more lights I'd see. It would state that it is good if I just put the tip in. Therefore, I cleaned it off and sprayed it with DOT 3 in my father's car (which also uses it) and the same thing happened. Negative feedback is more likely to be given the further you put it in. The brake fluid tester is put in the tester if you refer to videos on brake fluid testers. The reading can take a few seconds for it to give you (it takes a few seconds) and THEN it gives you one. I don't care as to what this testing company gives you as a result.

The device seems to be pretty handy
4/5

Batteries are used in this tester, one AAA type pen light There is a compartment on the side of the tester where the battery is placed. In some cases the battery compartment cover has a tight alignment, which can be problematic when using certain batteries, as when replacing the cover the battery is pushed This is because the contact spring is weak enough to allow the battery not to engage with the upper contact in order to complete the circuit. It is nessisary to immerse the entire tip of the pen in the liquid to induce a chemical reaction only the two metal tips are necessary. Do not put the whole pen in water. A thin piece of conductive foil can help reduce the gap. tested the function of the tester by first submerging it into a cup of plain tap water to determine whether it functioned properly. After testing the meter with two cups of cooking oil, I decided not to use it. The result is positive only if one green light is illuminated.

I like the product very much
3/5

We will continue to do this until something In my line of work as a dealership technician, we use a chemical reaction test strip to check It was important for me to find a device that could check brake fluid condition more rapidly, and this provided me with exactly that. In spite of this, the plastic around the tip of the pen disintegrated within a week. In my opinion, the toolbox could have been improved with this addition for $9. The manufacturer needs to improve the materials used in the manufacture of this to make it stronger and.

An excellent diagnostic tool
5/5

If you're doing brake work and you need to know if your brake fluid needs to be flushed, this is what you need. The tool is fantastic for diagnosing problems. The writing style is simple and easy A simple and easy to use tool. In one instance, I used it on a bottle of brake fluid that had been left open to see if it could detect moisture. If brake fluid looks clean, it does not mean it does not contain a lot of moisture. This is especially true in wet climates. Do not forget to get one if you do not have one in your toolbox.

It should be made of a material that is resistant to brake fluid
3/5

It is an AWFUL design! After two times of use, the moisture tester worked as expected. I had trouble using the tool after the probes came off in the cover after the third use. A flush with water was performed after each use of the probe. There was enough brake fluid in the hole through which the probes came to compromise the plastic, as the probes interfered with the In light of the fact that their product will be in direct contact with brake fluid, the manufacture should use a far more robust material.

There's trash everywhere
3/5

It was total trash picked these up for my toolbox but no use got them since they broke off as soon as I opened them. I am a mechanic and thought that these would be a great addition to my tools but when I used them 2 days after I purchased them, the tips were broken
Not worth the money and they are easy to break. Those are not the kinds of products I would recommend.

As it is testing multiple brand new fluids that have yet to be released, I think the tester is not accurate and useful
3/5

A few brand new bottles were tested with the tester, and each new bottle indicated water at 1%, while an open old bottle measured 2%. Tested 4 vehicles and it calculated 1 year old fluid at 1%, one at 2% and one at over 4%. There are different brands as well. The tester is a waste of money and shouldn't be recommended.
