I can now die peacefully understanding and designing my brake system for my senior project! You have saved so many engineering lives!! Thank you so much keep up the good work.
Yet again learning more in like 5 minuets from a video than school teaches me in a year... so sad but very helpful thank you for this simple easy explanatory video!!!
Don't care about the voice robot, only the information and how it's conveyed. Fantastic content - exactly what I wanted to start learning some basic mechanics. Subbed. Edit: Just noticed you stopped making videos ages ago. That's a real shame! This was brilliant.
I've watched several videos and none have explained what causes the caliper pads and piston to return to their pre compressed state when you release the brake pedal.
+tzone but if the system is sealed then the brake pedal return to its upright position the fluid would cause the piston in the caliper to back off of the disc and back to their original positions
That's what I thought too but investigating further apparently there's a square gasket seal that sits in a recess in the piston cylinder wall that rolls when the piston is compressed and unrolls when the brakes are released assisting the piston back by the smallest fraction to release the rotor...apparently.
Hi both. We are working on a series of technical trainings on clutch, transmission and brakes. In terms of the piston return, it is achieved by an inner seal or "Square cut seal". When the brake is engaged, the seal flexes or deforms. When hydraulic pressure is released, the seal reverts back to its natural state, taking the piston back with it. We explain this with animation in one of our videos. Once up you may wish to take a look.
That was great. I found the answer to my question , if a piston presses only on one pad and forces it against the disc rotor , how the other pad works ! Now more wonder !
This really throws a lot of light when considering the dynamics of the brake pedal over it's movement, thanks a lot!! Even if now is easier to consider, an animation presentating it would help those with doubts on this!
very well explained learned stuff I never knew before hand like how when force is applied to the left piston the fluid will transmit a force to the right piston force
It was awesome .....do more videos regarding engineering stuffs ... you are doing awesome ...even a non mechanical guy can understand now by your explanation ...
I saw so many this kinds of demo. I am sitll confused how the pistal and pads go back to original position (open). Is it still driven by the hydrolic force or driven back by something like spring? All the demos only clear the first half procedure: pistal move forward braking. How is it driven back, reset to the original position (open)?
There is a rubber seal on the caliper that piston slides through. This flexes slightly outward when the brakes are applied and retracts the piston again from the rotor when the brakes are released. The movement is very small, but just enough to keep the brake pad off the rotor.
Flawless, two thumbs up! Thank you :) Can you post more lessons like; how the steering, suspension, Electrical devises or Hybrid engines and transmission systems work?
Frickin awesome, I was curious I couldn't picture how it works in my mind, man I hope I'm lucky enough that I don't need to replace the entire caliber or one of the brake lines and it's just the pins that need grease.
thanks for the great video but i have a question, what pushes the piston back when brake is released because i disassembled the caliper on my car and pushed the brakes so the piston extended out and i had to use a c-clamp to get it back in, i mean why doesn't it return back when brakes are released and doesn't that make the pads in contact with the rotor all the time ?
+AutoTech Lab Thanks i was just confused because my right wheel brakes seem to be slightly stuck and the wheel doesn't move on low rpm while the car is on jacks i thought this might be the problem but i'm guessing now it could be the master cylinder, another question can a faulty master cylinder cause the brakes to stick on one side only or does the master feed both sides at the same time, and are the 2 pistons inside the master for right and left or not ?
The piston is sliding on a square seal located in the bore this seal is what brings the piston back.. As the piston moves the square seal will twist slightly when the brake is applied and when the brake is released the seal will bring the piston back so the seal is flat..
Amr Teko omg i have the same question. Still dont know what is 'square seal' and where it is alocated. I need to check that part on my bike. Doing investigation... would be nice if someone can give me some hints..
What gets the brake pads off the disk? Drum brake pads have a spring that push the piston back. The piston on the disk brakes is not being pushed back by anything.
There is a rubber seal on the caliper that piston slides through. This flexes slightly outward when the brakes are applied and retracts the piston again from the rotor when the brakes are released. The movement is very small, but just enough to keep the brake pad off the rotor.
My mechanic said that the brake pad and the disc should slightly touch when the brake is not apply, Is it correct? When we step on the brake pedal, they will further be pressed together.
Hello. Your presentation is perfect. I'm using it in my classes. Since I am from Slovenia, I would like to alter the video with Slovene expressions and Slovene audio. Therefor I'm asking for your permission to do so. The video will be used for educational purposes strictly. Thank you in advance for your answer.
awesome, didnt understand how the outter brake pad was being pushed in now i see, my pins are frozen stuck no wonder outter brake pad minimal wear and only in one corner thanks
My understanding is that the cross drilled holes are not to dissipate heat, but to reduce brake fade by allowing the gas that is generated by breaking to dissipate. Ventilated disks (where you have a gap between the forward and backward facing rotors) are what help with heat removal
Is it really incompressible fluid? I believe compressible fluid will also exert pressure in all directions. The key is only enclosed (without any leak)
Pls make a veido on ABS breaking system and what is adventage of using hydraulic breaking system against wired breaking system...... And thanks for such a great veido
But what causes the pads to pull off the rotor after releasing pressure on the brake pedal? The reason I ask is that when I did my front brakes, I had to dremel out the portion of the caliper bracket where the pad guides sit, and I think I went a little overboard. So, the pads were a bit lose in the bracket. Is this a problem? Does the assembly count on the pads being held firmly within the brackets by friction (just the force of the fit of the pads in the bracket)?

That would appear to be a yes. It seems to be a push, whereas on the outer it is a pull. The frame with the piston moves, which is what I needed to get my head around. The used discs I have seen are always more worn on the inside face. Similarly more rust appears on the inner face. I guess the piston must be designed to retract slightly when the pressure of the foot on the brake is released. I would tend to think if the inner face deteriorates quicker, why not make it a bit thicker than the outer? Doesn't seem to be the way it works...

Very good video. I really hate it when people use that robot voice but I love how easy it was to learn from this video.
i really love the robot voice. maybe the guy who made this video is shy, and doesnt want to show himself to thousands of people.

Brilliant! I'm glad you used an equation to explain Pascal's Law, that was more useful detail than I expected. Good work!
This is a proper explanation unlike other videos which miss the point of the different p I ston sizes !!!
Your presentation and explanation is touched my heart!
Now I knew it that we can develop ourselves just because of you!
This is an absolute college classroom level video of how disk brakes work! I love the graphic representation!

One of the best explanation which i have seen on RUclips...
I want to give a applause speech for this channel:
I'm speechless🤣🤣
The Pascal's law in the brake system explanation! Wow!
I knew the basics but knowing EXACTLY down the math/physics explained this well is amazing
I would like to give this robot a beer. Good job.

How great. That was amazing. Perfect explanation. Please continue your lessons. 👌
A clean and nice explanation. Very much appreciable.
Explained it very nicely, crystal clear, Interesting Engineering and Science and Technology.
Very impressive video, clearly show how break works. I am looking forward more presentation from you guys.
It's really awesome engineering. And thank you sir for explanation with animation.
This is unbelievably good explanation. With the visuals and easy to understand choice of words, definitely going to subscribe. Very good.
very well explained learned stuff I never knew before hand like how when force is applied to the left piston the fluid will transmit a force to the right piston force

Best video to understand caliper working
Phenomenal explanation of floating type caliper disk brake absolutely loved it 👍
excellent explanation with law ,detailed explaining helped to understand easily with the names of different parts.
Thanks for your hard work on this video really appreciate
Very helpful. Congratulations.
Very useful video our company is brake manufacturing

Bro the break piston have more elastic spring it pushes bake.

Wow Good video, Could you explain how piston returned to it position. Because there is no spring
I like the computer narrator voice. This is my favorite voice
your plays an important role in understanding the concept better
subscribed 👍👍👍
What gets the brake pads off the disk? Drum brake pads have a spring that push the piston back. The piston on the disk brakes is not being pushed back by anything.

Dear bro what a good video it's. Thanks for that.
Nice explanation!
this was amazing fantastic... i dont have words to explain
a super clean explain..
thanks very much.
Really tnq to post this video..very useful me this video simple explanation
What releases the brake pads and keeps them away from the rotor until the pedal is pressed again?
Thanks for great explanation with good animation
My mechanic said that the brake pad and the disc should slightly touch when the brake is not apply, Is it correct?
When we step on the brake pedal, they will further be pressed together.
2:40 drilled holes are not for ventilation, they only help in evacuating gases that the pads produce and weight reduction
best explanation ever!!

it is very nice vedeo for teaching and knowing about disk brake
waiting for next video, its awesome works :) thanks a lot...
Good explaination.... Hats off
Excellent forensic explaination
great explanation, thanks
Excellent explanation.
after they have squeezed the rotor, what makes them go back to their original position.
Highly informative, but sir I want to know that how the 3d animated video was built?
He, most likely, made it in Autodesk Inventor; Autodesk Inventor is commonly used in industries to create 3D "blueprints" for products.
Excellent video!!!
so what would cause the outer brake pad to wear down to metal while the inner brake pad is nearly new?
Fantastic video Sir
Hii sir i love you're videos
great video!!! which software you used to do this animation?
Thnks for your valuble class
Which type of bearing is installed at the end of the sleeve of
a release brake?
plz answer
Thank you for the great explanation.

Never knew how the outside pad gets forced onto the rotors, makes perfect sense now
Great explanation and animation
How does the caliper attach to the wheel? if the rotor spins doesnt the caliper also spin with it?
What if the caliper bolts are not screwed in all the way because of bad threads, can this cause a wobble?
Beautifully explained!
good explanation and animation
Is it really incompressible fluid? I believe compressible fluid will also exert pressure in all directions. The key is only enclosed (without any leak)
If my high school teachers taught me algebra like this, i wouldn't be so dumb. This is amazing
Pls make a veido on ABS breaking system and what is adventage of using hydraulic breaking system against wired breaking system...... And thanks for such a great veido
wire would stretch or snap from the force needed to stop the car
It is an wonderful explanation...........
very interesting.Thank you for sharing
So good. Plz upload more videos
Really great work
can you please tell me how was this vedio made as in which software did you use to create the simulation of a braking system??
This makes so much sense😳
Good explanation 👍 please do more video
But what causes the pads to pull off the rotor after releasing pressure on the brake pedal?

Thank you. This was very helpful.
Once the brake pads clamps on the disk to brake, what force retracts them away to stop braking?? 🤔
