+worldtrades Ironic, heh. Straight and to the point is my style. You'd probably want more detail to understand the background if you were in school though.
This is the best 3 minutes and 17 seconds I've ever spent on UA-cam. Technical and informative with no nonsense or stupid music. Great work, thank you!
Finally a video showing how ABS works instead of showing what it does!!!! This video moves pretty fast (thank goodness for pause and rewind) but it's so awesome! Exactly what I was was looking for! Thanks so much for this informative, straight to the good parts, video!!
Maybe 4 years ago they didnt put computers in ABS modules like they did in 2011 on the Ford Fusions..............................................................................
Good video. ABS typically has 8 valves. This unit has 12 so it includes stability control functions but there are still only 2 valves per wheel. The other 4 valves are needed for directing fluid flow within the hydraulic assembly and isolating the master cylinder. ESC can pump the fluid in either direction while abs only pumps fluid back to the master cylinder.
Damn......I have tried to understand ABS system for many years, and this guy just made me understand it 100% in under 3 minutes....you are the best sir!
Nice video. No wasting time screwing around while we have to sit and watch every screw being taken out, no camera jostling, no out of focus, you explain everything without mumbling, sniffling, "aah-ahh-uhmm", no gay music...shit, you should do a video on how to do UA-cam videos!
The ABS has 3 valves per wheel to Isolate, Dump or Pressurize each wheel circuit as the ABS module sees fit. The ABS pump runs every time the module requests it and it is used to pressurize any circuit the ABS wishes to. Great video
I have 40 years in Aviation working on abs systems to far more wheels and amazed how auto adopts so much from this. I want to say your video was the most detailed learning experience to show someone with no idea how it works to at least understand this complex system. I hate that they make them with such crappy parts (miniaturized relays that can't take the abuse they need) solenoids that using lower power and much smaller currents can fail case in point Corvette braking system in abs. cost for new one $1400 bucks for a 6 dollar relay known for going bad. I miss analog in its rawest form of durability. We live in a digital world and analog has to be shrunk to make it work with less current. My point is Bravo to you for doing such a great video and the explanation was spot on.
My lexus hybrid had an accident & the automechanic guy said they'd have to change/repair the ABS, so I got curious to know more and voilà your 3mins Masterclass enlightened me beyond measure. Thank you for this masterfully & straight-to-the-point ABS-for-dummies video. Cheers sir 👍
this is perhaps the best presentation so far . I have had a jammed ABS Valve on my 2008 Citroen C5 ABS module . soaking a towel wrapped around the aluminium valve body of the ABS module with boiling hot water and rapidly tapping the aluminium block with a small 2 oz hammer has freed off whichever ABS valve which was stuck in the operated position .I now have brakes and a pedal which no longer sinks to the floor . opening the caliper bleed screw is super important when installing new brake pads . Contaminated brake fluid passing through the ABS valves will almost certainly cause the valves to lock. There will be no ABS fault showing . My Foxwell NT630-Plus ABS scan tool was indicating there was a valve which was not operational .. an audible CLICK should be heard when each solenoid is activated . I have a second hand ABS module coming from EBAY and I intend to fabricate a manifold to test the individual valve operations .
That was the best most succinct and accurate video in the universe. This is what a UA-cam video should strive to be. I was looking for information, I got the information without all the bumbling around. Thank You.
This is a very useful video in terms of showing what is inside an ABS modulator and what to expect if you take various parts off. It's not great in terms of explaining how ABS works.
Hi Fella' I have been watching other technicians stripping ABS pumps, you are the only one to me that has done a great commentary and visual explanation of the operating system. so her goes my attempt at fault finding on the ABS pump and control module. Thanx. Tom in Ayr Scotland.
Hey man... I just want to say thank you... your video I simple and yet very informative... even someone like me that is not very mechanically/car minded can understand what is going on... I wish all UA-cam videos were like yours...
Thanks a lot bro I was searching for a detailed video like this. Very helpful I'm really into ABS brake I just love it. I really search in depth about how ABS system evolved
Excellent. Makes me think I could easily bypass the ABS system by simply tying the lines from the front and back of the master cylinder to the front and back brake lines.
there is no such thing as master cylinder input and return. there are two separate brake systems in case of brake failure, master cylinder has two chambers built in.
+Marijus Marcinkus I agree, thanks. The fluid flows back into the reservoir when the pedal is released. The power steering system on the other hand, has a supply and return.
@@mars188 No. It controls valves and a motor. If a wheel is just about to slip (or already did), then the pipe towards the wheel is shut off. (It is a default-open valve.) If desired effect is not achieved, then the valve to the motor is opened. The motor forces brake fluid back to master cylinder, reducing brake power on that wheel. When stabilized, this default-off v. is closed.
Great information . I see online that several places rebuild these units . Some use a module in addition to the pump and motor . These are expensive as new . I can see why a rebuilt unit can save money . As long as the quality is there .
Actually, the motor only makes pressure in ESP operation, since no pressure is applied on the brake pedal. The main purpose of that motor is to flow the excess brake fluid from normal ABS operation (when ABS kicks in, some of the fluid is released inside a chamber and has to be resent to the brake fluid reservoir when the pedal is released)
Its dosent need the motor for returning the fluid.. this dosen't make any sense.. for that you could just run a line to the fluid tank.. if the abs kicks in.. the valves release some pressure.. if you are downhill and keep the foot of on the brake pedal.. the pressure realising will eventually make the pedal end on the floor. The motor is there to rebuild the pressure when the wheels regain grip and the ABS stops.
This video is so good, showing the ABS motor is really a scarce thing on youtube....the downside is that the explanations could have been slower and a little bit elaborate....
Of course, this unit's electric motor is entirely serviceable with screws fastening the housing on. Then you have manufacturers like BMW who TRY to make the motor housing on ABS assembly factory press-wedged together so you have to file parts of the aluminum valve body to free the housing then drill holes in the housing in order to access the tongue of the clips that hold the motor in the housing. Great informative video on ABS module assemblies!
Great video!! Thanks a ton mate. Straight to the point, and explained exactly HOW does it work, rather than WHAT it does like in the other videos on youtube!!
man, you are awesome in teaching. i really appreciate your videos its so informative in a way there would be no confusion understanding it. good job sir !
That speed sensor system is a magnet that has the tone ring passing by it. This induces AC voltage that the computer reads. Faster the tone ring moves past the sensor, the higher the voltage. Simple troubleshooting is to put a voltmeter set to read AC voltage on the pins in the connector. Jack up the wheel and spin it. This should show a voltage.
Thanks man , you've solved this puzzle for me as I was thinking and trying to get my head around it , your explanations are right on target and very simple to grasp , UA-cam should've shown me your channel long time ago since I watch videos like this pretty much all the time , although this is the first video of yours which I just watched , I can confidently say that you know what you are talking about 👍 .
Top video! Ive never bothered to mess with an abs pump before but that was a perfect explaination of wtf goes on in there. Im sending this to my mate with a v rod cos his has fuct up. :)
ABS needs only 2 valves per wheel, this unit that you have has also ESP, which has additional 2 valves for each braking channel allowing it to have controlled pressure on each separate wheel :)
speedkar99 I'm watching all ur videos.as I get time...u got good stuff..and people like u are worth gold...im a motorcycle mechanic.but work on cars also.if it has gas and a spark plug it's the same.exept wankel engine.I know that one too.if I need advice I will message u.thanks again
this is by far the best explanatory video on ABS on youtube
+Burak Soner Thank you
could not agree with you more.. spot on .. really the best explanation.
i agree
And it got watched by 109 people right after being dumped by the boyfriends.
@Burak Soner The Best brother. the guy explained it like you can use it for any school.
I'm taking a $5000 automotive course with one of the best schools and your video explained everything MUCH better than anything I've learned.
+worldtrades Ironic, heh. Straight and to the point is my style. You'd probably want more detail to understand the background if you were in school though.
Welcome to UA-cam University😅
Wow, I didn't think it was possible to explain this much about ABS internals in just over 3 minutes. Extremely well done!
Thanks, short and to the point is how its gotta be
This is the best 3 minutes and 17 seconds I've ever spent on UA-cam. Technical and informative with no nonsense or stupid music. Great work, thank you!
is it still true?
Finally a video showing how ABS works instead of showing what it does!!!! This video moves pretty fast (thank goodness for pause and rewind) but it's so awesome! Exactly what I was was looking for! Thanks so much for this informative, straight to the good parts, video!!
+Daniel Dickey Thank you for the feedback. Yes a bit fast paced so you don't fall asleep.

wow, great video, well edited and filmed and straight to the point. Wish more videos on youtube were this well made. Cheers.
+Star Star Thank you
There are, but UA-cam rewards/favors longer videos, especially those over ten minutes.
Agreed
Good video. ABS typically has 8 valves. This unit has 12 so it includes stability control functions but there are still only 2 valves per wheel. The other 4 valves are needed for directing fluid flow within the hydraulic assembly and isolating the master cylinder. ESC can pump the fluid in either direction while abs only pumps fluid back to the master cylinder.
Good to know
3 minutes of pure, condensed knowledge. Phenomenal video.

100% correct.It didn't have the 5 minute intro of boring bs either!
+Matty Bt thanks
+Andork Kuomo Thanks that is my style!
incredible, you explained an entire system in 3 minutes and made my understanding of it jump by 300%.
I like the way each wheel has three solenoids, it's very loving.
Sure is
The ABS has 3 valves per wheel to Isolate, Dump or Pressurize each wheel circuit as the ABS module sees fit. The ABS pump runs every time the module requests it and it is used to pressurize any circuit the ABS wishes to.
Great video
Yup
Thanks
so what your saying is the owners of cars with abs.. have three wishes?

This channel is really underrated. Thanks for explaining on abs n cruise control best ones.
These 3 minutes & 17 seconds was really worth it
Glad it helped!

Where were you all these years? The video is 3 mins but full of information.
Hi
I've been here all these years
Where have you been? 🤣
Thanks for a clear and concise explanation of ABS system.
Awesome. I'll have an updated ABS video by the end of this year.
This is a really easy to understand video on how this works, thanks for the video!
Glad you liked it!
Thanks Bro your a genius
you made it is to understand something that seemed so complex.
