Questions & Answers

Is there a list of all the fluids this can test? Do you know if it is possible to power steer?

There is no other brake fluid

What about DOT 5? Does it work?

The silicone base of dot 5 is moisturizing and antibacterial 5 in the paragraph above. Those who hold moisture will hold it. The moisture content of this product is measured

Why does this model cost $8 instead of the previous one. There were 91 cents and six cents. A 1999 model, the ?

It's impossible for me to tell the difference between the two, only that the one I bought fell apart.

Dot 3 and 4 brake fluids can be tested with the brake fluid tester?

It appears to do so based on the item listing. Because I only used it on DOT 3, I am unsure if it is a universal plug. It should work on all DOT 5/silicone brake fluids except one DOT 5/silicone brake fluid it doesn't

Selected User Reviews For eOUTIL Brake Fluid Tester Pen, Hydraulic Fluid Liquid Oil Moisture Analyzer with 5 LED Indicators, Auto Brake Diagnostic Testing Tool for DOT3 DOT4 Brake Fluid

The knowledge of this tool would have made my life a lot easier many years ago
5/5

As far as I can tell, this tool works well on my vehicles. By this point, all of my vehicles had fresh brake fluid recently installed in them, and I had tested it, and it gave a good As I continue to monitor my fluid levels, I'll also make sure to keep an eye on my friends (so quick to check for a procedure). Additionally, I conducted a comparison of a brand new fluid (two days old) with an established fluid (more than a year old). Both instances of testing indicated good results (less than 1 % moisture content). This gave me a confirmation of my results to use for future tests.

I've already saved myself a lot of cash on Simply put, it works like it's When you push the end of the pen like a pen, it turns on with a green led, powered by an AAA battery
5/5

It comes with a color coded LED light that shows the fluid level. I like this one because it works with different kinds of brake fluid, DOT 3, DOT 4, and so on. I was not sure if all would do it, but this one offered that information. My two vehicles have been fitted with it so far and it works perfectly! In one of my cars, the fluid had to be changed, which probably saved me a great deal of money, since the fluid is known to retain water and deteriorate your brake lines and parts over time. As far as our tester goes, it does seem high-quality and like the sort of thing an actual mechanic would use all the time.

I've tested it in a cup of water and with a AAA battery
5/5

It seems to work fine. The 4% indicator instantly illuminated and showed red. After that, I tested my brake fluid in my 2016 Nissan Rogue and it showed As much as I could squeeze into a small cup, I squirted it using a baster. The tester still displayed 1% after adding a few drops of water with a thin syringe. The solution went from 2% to 4% after an additional small amount of water. There was a great deal of consistency between the readings. My tester is accurate, and I am pleased with its performance. I was not surprised that my 51,000 mile vehicle had been driven gently in the arid U. S. In Southwest, only 1% of the population was tested. I don't think that's true for desert vehicles. That's why I bought this tester after a Nissan dealer tried to sell me a brake fluid change and other services. Most shops and dealers can only be trusted to try to get as much money from us as possible. I'll wait until next year to test again. My brake fluid is still very gold in color and my brakes work perfectly, so I don't think I'll need to change it. It will be changed by me when it makes sense.

'Worked great' idea, but 'bad integration (took 3 business days' It takes her days to break herself)
3/5

It worked the few times I used it. I had another one I loaned out and it never came back, so I ordered this one to replace it. There was a slight difference in design, but it worked well enough for the three vehicles I tried. My garage tester drawer was in pieces when I opened it today, so I went out and dealt with it. The answer is yes. As soon as it arose, it broke. It is probably because they use springs to contact the test pins, so the spring pressure was strong enough to overcome the sheer strength of the thin plastic (there's an indentation made in the plastic body to snap the cap However, there is a problem. The plastic in that area is extremely thin and probably made of In other words. As a result, it broke. The problem with this tester is quite common, as I have seen in other reviews. I would not have expected this to happen, but I have looked at other reviews. If you're looking for something not Chinese, try this It continues to be made in China, or at least of higher quality than previously.

After one use, it basically falls apart on its own
3/5

This is a tool I have used once and kept in My mouth was bleeding the next day, when I saw the tip had popped off, and the plastic had completely worn away. I had not touched it in any way. There is literally nothing more to say about this Please do not throw away this product. Responses to a message from the seller were given within a day and a refund or replacement was offered. I am bumping up the score to 2 stars for good customer service, but this product is defective.

The test kit makes it easy to test brake fluid
5/5

I highly recommend it. I am very pleased with this product. The method worked with new brake fluid as well as with a cup of water to see if it actually worked. Many customers have reported problems with the plastic around the probes breaking over time. I recommend that you always clean the test pen with denatured alcohol after use to remove any traces of brake fluid that may be left behind. If you do that, you should be able to prolong the life of this instrument.

You may even notice dark or black brake fluid in the master cylinder if your calipers are rusted due to contaminated brake fluid*br> early warning signs of a potential problem can even be seen as soon as the calipers are rusted
5/5

It is not very costly to test your brake fluid and to purchase new calipers, so you may as well keep this on your maintenance list.

A method to measure the moisture in brake fluid accurately
5/5

This reading got me to 1% right away, which is very helpful, as it tells me that the brake fluid is fine. Measures voltage, which is correlated to volume of water in a container. Not difficult at all.
