These work great, I use them all the time at our shop, don’t let the big dealers or shops say you need to change every 2 years, just test it with this pen first or brake fluid test strips.
my mechanic did a brake flush on my 2005 chevy express 3500 (motorhome) at 22,000 miles. Now says a year and 11,000 more miles says there are contaminants in it and wants to do another. Does that sound right?
@@alive-awake absolutely not right. Don't listen to him. Every 2 years is the absolute most often you need to change it. Don't care what anyone says... unless you're taking you car to a race track or something.
Never knew there was a brake fluid tester. I have seen a brake line bleeder, but never used one. Always did it the old fashion way, 2 people. Thanks for the educational and interesting video. Thumbs up
Many brake manufacturers recommend against conductivity-type electronic testers as they may give false readings. The better, and much more expensive, testers actually heats the fluid and determine the moisture content based off of the boiling-point.
You video was very clear and you only dipped the gold colored tips in to fluid. Other vids the person dipped an inch and a half past the tips. Someone commented it could give a misread.

The brake fluid still looked quite nasty after you pumped a few times. Shouldn't you pump until the fresh fluid is coming out before you tighten the bleeder again?
There was nothing wrong with the fluid. If the fluid is old & discolored, you'll be able to see the new fluid show up at the bleeder valve very easily.
@@electronicsNmore Nothing wrong? Really? It looked quite dark. I mean you even showed with your multimeter and the brake fluid meter that the brake fluid should be changed, yet you say there was nothing wrong with the fluid? Granted, it's an older video and you may have forgotten about its content, but to claim that there was nothing wrong with the fluid, is a bit of an overstatement imo.
Great tutoring video. I am going to purchase Brake fluid check valve. My concern is how to choose the correct one. Is the Bleeder screw valve has the same diameter for all vehicles? I know, that different tool size is used to unscrew the bleeder valve .

If enough moisture is absorbed by the brake fluid, it can accumulate in the lower portion of the reservoir. Only test to the depth in the directions. Thanks for watching!
@@electronicsNmore Thank you for the answer, I really don't know. If I only touch the fluid only with the tip of the sensors it is 1%. If i immerse it halfway it is 2%, if i fully immerse the electrodes and maybe touch the fluid with the plastic part of the tester then it shows 3%. I'll try it with a resistance meter tomorrow.
I'm experiencing the same issue. I'm not sure how much I can trust this unit. I would not buy it again. For myself, I will just stick with replacing the brake the fluid every 2 years or as recommended by the vehicles manufacturer.
Good vid, thanks. Only part I didn't catch is how to know when the good brake fluid has reached each brake before closing the screw. Are you resistance testing at the bucket to know?
I can tell by the color change, but you can also test the fluid as you go to see when the level shows the low moisture range on the tester. Thanks for watching! Be sure to rate thumbs up and share my videos with others.
Tuna Fish Less than 5M ohm. I only showed you what a good reading looks like with a DMM using new brake fluid. Good fluid is usually above 5 M, old is below.

Some cars have a hydraulic clutch reservoir. Care read manual since some use oil some use brake fluid.If you by mistake put in wrong fluid you will need a new clutch master and actuator . I made that mistake on a eurotrash car.שלום
@@electronicsNmore thank you for the reply. since i am not a mechanical engineer i had to look it up what that means. i found this: " If the brake fluid becomes unable to control the pH or other corrosive elements, the rubber and metal parts will deteriorate over time." well, i am just after a big service and the mechanic claims that he changed the fluid. do you think he lied to me?
What car is it? My 20 y old corolla with original brake fluid wss still under 1% water. But I change some from reservoir to get enough anticorrosion additive
@@electronicsNmore thanks to let me know. Different cars have different degrees of sealed brake system. But I agree, brake fluid flush every 10y should be required. Before corrosion start to destroy ABS or valves.
Yes, but usually you can see the water. The best way to test for a blown head gasket, is to test the engine coolant with the kit shown below. :-) Thanks for watching! amzn.to/2qQtPGy
Hello. When I made the video, I had the brake fluid sitting on the counter a while while I was filming. I live in south Florida where it's very humid, so it may have soaked up a little moisture. Ideally only the green LED should be on. Thanks for watching!
Hi Andre. Those check valves may be damaged by the brake fluid. The aluminum type shown in the video has a spring and steel ball pushing against a seat.

Brake fluid is generally clear when you buy it. After a few years it starts to look dirty. That is the way it is designed to work. If it doesn't look dirty don't worry.
Ok just looking at these types of testers and wondered about how accurate they can actually be. For example: they work purely on the resistance tested across the terminals. However this resistance is weaker in normal moisture ie rain water and so on due to contaminants in the water, but what if you accidently some how managed to get distilled water in the brake fluid, the tester wouldn't pick this up, due to the fact that distilled water is non conductive. So the tester would probably read that the brake fluid was good when in fact was bad. Has this been tested, for sure it's unlikely to happen but it is potentially a test that could confuse the testing device. However a tester with an actual meter as in the multi meter you would get an indication that something was a miss. It's just a thought.
Yes I know it's highly unlikely to ever happen I was mostly just curious to see what kind of results you might get should distilled water end up in brake fluid. Would this tester actually give a false reading?Something I will have to test, as I say I was mostly just curious more than anything else.
Ok just had a look at your video on pure water.And yes I know distilled pure water has no conductivity that's why I suggested the idea of doing the test with the tool to see what kind of result you might have gotten.Anyway something for me to test it was just a curiosity.Good video by the way.
electronicsNmore My dad asked me why does his champion motorgrader had to use mineral oil for brake fluid i told him they probably got a good deal on nos military surplus brake components the old deuce and a half and the five ton used also ,they where acquiring parts for designing and production I've seen this before on small production or build to order machines
This channel used to be all about DIY and finding simple, inexpensive ways to do things yourself. Now it's just another infomercial channel for Banggood. There are too many videos trying to hawk some stupid Chinese gizmo. Just put the brake fluid on a hot spoon and see if it sizzles.

Only thing I will say is unless precautions are taken, air can be drawn in around the threads of the bleeders. Otherwise great video!

Get a "mighty vac" tool to bleed system.Also some ABS need to be pressure bled.Carefull. Excellent video to help people. Thanks!
Yes, the vacuum bleeding tool is the best way to ensure that all air bubbles have been removed from the ABS pump/valves.
we can ever notice the new fluid coming out....you need to be more pacient... you must remove ALL the old brake fuid....
Excellent job on the video! Thank you for posting.
great... learned something new
using directional valve.
Отличное видео! Заказал трубку с обратным клапаном, благодарю!
after i get the pen, do i check the fluid when the car is cold or warmed up??
I don't think the conductivity changes with temp, but I would test it before driving. Thanks for watching!
So now this is the best video to change brake fluid well done 👍

Really this first time I heard like taste for break filed
Thinks
dont taste it.. you will die
I tried this but found my bleed nipple won't open. It looks rusty and I don't want to damage it.
Apply penetrating oil and wait. Then use FLAT jaw vise grips to remove the bleeder bolt. Replace the bleeder bolt with a new one.
electronicsNmore I've tried penetrating oil and heat and everything else. It's a 13 year old car so might need new caliper.
Bought them pen it sucks on clean oil it needed change
Mine works just fine.
