How Car Brake Works

[@MrDownslider]

I just learned more in this 2:30 min video than I had in my 40 years as a know-nothing about cars.

[@inuysha360]

This video is a perfect example of how brakes work. Nice tip for anyone who doesn't kmow anything about cars or wants to know about cars.

[@ryandraeger9089]

Extremely educational, very good animation of a front disc rear drum vehicle

[@AutomotiveSystem]

The Vacuum Booster acts as a servo mechanism, which adds to the force already developed by pressing the brake pedal. The fluid pressure is actually developed by the master cylinder due to the compression process explained in the video.

[@AutomotiveSystem]

The operation of the clutch is entirely independent from the application of brakes. In case of manual transmission, we apply clutch pedal and shift to lower gears when braking to ensure that a required torque is maintained. In automatic transmission, the torque converter does the same job without the need of clutch pedal. Without pressing the clutch pedal, the clutch and flywheel are both in contact, even if the brakes are applied. For more on clutch see our transmission system video. Thanks!

[@madmadmadhur1]

Very good video. Perfectly created and very easy to understand braking system with this video !! You should answer what someone asked: "if handbrake is not holding car on incline, which brake is to be replaced"

[@fuzzynuts4319]

Usually the rear brakes

[@stereopolice]

00:55 oops the primary and secondary pistons (in this video) appear to have over-traveled the brake line ports, which (in this video) have equalized the brake line pressure with the compensating ports (meaning the braking action will fail). In reality, the primary and secondary pistons will not over-travel the ports, thus maintaining brake line pressure. Just FYI for those using this vid as an education instrument. Regards ...

[@calvinbafshoe2626]

Wow! thank you so much for such an informative video 😊. It's short yet powerful at the same time. Saves us a lot of time

[@AutomotiveSystem]

Thank you for your feedback. This video also clearly shows the energy conversion at 2:06 where it is stated that the brake shoes rub against the drum, generating friction and converting kinetic energy into heat energy. We hope that you found your answer!

[@smritisrivastava9178]

Good information but listening to the explanation increases the retention of the information in our memory so u should add the voice explaining it would worth u

[@Imrankhan-ve2cm]

Simple & Clear......... Thank you very much for sharing this.... I hope there is no need for sound. Video itself explains it an a clear manner..

[@AutomotiveSystem]

Thank you for your feedback Andrew! We will try to explain the servo system separately in another video.

[@douglepera391]

Great animation on how car braks work.

[@AutomotiveSystem]

The function of a fixed caliper is very much similar to the floating one. The only difference is that the position of the caliper remains fixed and the fluid causes both the brake pads to move inwards and apply the brakes.

[@Rawesome2013]

I'm no teacher or have an educational background. And it may just be the visual learner in me... but i swear videos without a narrator make you focus / go in depth to learn it since you really think you missed something.

[@artifexmusic]

does the brake fluid stay where it is or does it get send back to the resovoir? i think via a system it gets less pressurised

[@pilzj3263]

Didn't know the caliper-piston mechanism is the same as bicycle hydraulic disc braking system. Thanks for the explanation.

[@sanilawan2906]

As an automobile technology student I learned a lot, thanks

[@zakichannel7652]

fucking liar

[@mahem7679]

Greatly understood by the help of beautiful video and subtitles

[@gastonsanchez3273]

Hello, I would like to inform you that I will use your video for final elexamen of English that I will translate from English to Spanish. I ask you if you would let me resume it but subtitled in Spanish?

[@venusvences16]

wow what an awesome animated video! thank you guys it was very Useful! you guys should make more!

[@masonp1599]

9 years later, thank you

[@TheAnasgon]

and when we move the pedal back what happen to the fluid in the breaks canal does it stay there or back to fluid reservoir. and which force that make him back to the reservoir

[@teweldemhretab7593]

it cames back automaticaly

[@TheAnasgon]

how

[@tabetus]

+anas the hunter when you turn off the pressure,in the campana there are retracting springs and in the disc there is caliper which does the same thing.

[@TheAnasgon]

[@jakehix8132]

yeah, the act of taking ur foot off the brake pulls the liquid back in. the model used here makes it look like that'd be a rather messy process, which is likely why it wasn't displayed lol.

[@arpitakarkera]

Thanks for the video!!! Why are disc brakes used in front wheel and drum brakes in rear wheel? Why can't we use only one kind of brake for both?

[@JeffDeWitt]

We can. There are old cars with four wheel drums and most modern cars have four wheel disks. You often see a combination because the front brakes work a LOT harder than the rear ones, and disks do a much better job at getting rid of heat. Cheaper modern cars have rear drums mostly because it's more expensive to work in a hand brake with disks than it is with drums.

[@tigertruckerman]

great video,one thing that I dont understand when the fluid reaches the caliper and pushes the pads on to rotor how come it does not leak out

[@syncflipper]

that vacuum booster looks like magic

[@gketan30]

bt here it is not shown that how fluid get backs to its original position with this fast frequency

[@zhiarw]

+Ketan Gandhi the fluid is there never leaves(if there is air bubble in fluid it wont brake properly )

[@dhineshsivakumar7248]

When we take the leg from the pedal means automatically oil well go to the cylinder

[@johnmarshall4564]

Its very helpful to clearing out my fundamental knowledge about working of braking system.

[@toonietoonz]

Sooo, where am I supposed to cut?

[@Nourtzrt]

let me know when you find out

[@nagarajuab7593]

Hi

[@Darkshadow7081]

seeing the animation helped my understandin of brake systems

[@rishabhmaggirwar]

I have a few questions: 1. Why do we need braking systems for front and rear tyres? 2. The caliper unit in the front stops the tyre plates from the outside but the drum unit stops it from the inside, why? 3. For the rear braking unit, what is the 'drum'?

[@JeffDeWitt]

1. Because you want both ends of the car to stop at the same rate. If you didn't have brakes on the rear the back of the car would try to go faster than the front when the brakes are applied, causing the car to spin. Front brakes are needed because as the car slows momentum causes the body to try to go faster than the wheels, causing what is called "weight transfer", that's why when you see someone slam on their brakes the nose of the car pitches down. In fact most of the braking is done by the front brakes, that's why on some cars you will see disk brakes only on the front. 2. A disk system is simpler and is easier to service and build. It also cools much better because the disk is exposed to the air. There ARE drum brake systems that work on the outside of the drum, they are called "band brakes", but you will only find those on very old cars and trucks. More modern systems are inside the drum because it's more compact and you can get greater pressure from a hydraulic wheel cylinder. 3. The "drum" is an iron cover that goes over the rest of the rear brake assembly and may include the hub. It has a machined surface on the inside that the brake shoes push against.

[@CryptoBates]

Hey Jeff do the rear wheels have brake capliers too? if not or do how often do they need to be replaced.

[@JeffDeWitt]

+BadMadPlay Depends on the car, most older cars have rear drum brakes, not disks. Generally you just need to replace the pads, and even then maybe every other time the front brakes are done as the rear brakes don't have nearly the load the fronts do. However, I would be sure to flush out the system every time it's serviced.

[@CryptoBates]

Jeff DeWitt ah right, i notice my rear wheels have rotors so i guess they have brake pads too, i think i will have to replace them soon

[@JeffDeWitt]

BadMadPlay How many miles on the car and have they ever been replaced? Those rear pads don't do a lot of work and tend to last a long time. Before replacing them I'd take a look at how much thickness is left and the condition of the rotors.

[@AutomotiveSystem]

The brakes let go when the pedal is released. The entire system shown here works by the brake fluid pressure, which increases when the pedal is pressed and decreases when released. We hope that you found your answer!

[@tteuvky]

I have a question about how does car/van stop while applying brake. I have ford freestar which have 4 disc brake system. It run only with two front wheel which are connected to transmission or engine. So my question is when I apply the brake pedal, the brake are apply only on front 2 wheels or also on rear wheel?

[@moileung]

Nice, just like John said. Plus nice music background too.

[@duyvo2953]

Thanks so much for an insightful video!

[@umangshah9367]

when the brake is applied are the flywheel and clutch attached to each other?. when the brake is applied does the clutch rotate?. after the pedal is released how does the fluid go back to the resoirvoir??

[@seismic6402]

In this configuration the two independent brake lines do not appear to be diagonally opposite. As I understand it there can be different designs. Either way it still demonstrates the principle that a rupture of a brake line does not mean total loss of the service brakes. My experience of a rupture was that the brake pedal became very loose and the pedal became active much lower to the floor. There may be different designs that don't feel like that though.

[@kachamsaisumanth5335]

actually if we put force on break pedal, the contact vaccum chamber moves backwards right then how does the force get transferred in the front direction?

[@AutomotiveSystem]

Just to make sure that both the drum and disc brakes can be explained.

[@akhilb30]

After the break applied, how does the brake fluid goes back to the fluid reservoir?

[@umangshah8971]

only about the disc brake. when we apply the brake it causes disc to stop and along with it the hub and wheels also stop but does the axle stop its rotation as u r helpful let me ask 1 more after we release the brake,the force is removed from disc or drum, so how does transfer of power from engine to wheel is prevented. why dosent the car move why do we need to accelerate to start the car thanks in advance love your videos keep uploading

[@kik2186]

GREAT ANIMATION... THANKS

[@swayingGrass]

Hmm.. I think the vacuum booster piston acts like a pump. When pressed it pump fluid and when released it sucks back the fluid. Because, if it flows under pressure that means the fluid inside reservoir is under pressure, so how to fill it?

[@glenardmunson4961]

Other than the fact that the wheels are going in reverse, an excellent animation. BUT, this explains how brakes OPERATE, not on how they work. They work by converting kinetic energy into thermal (heat: energy, and I would love to find a good video/animation showing that. Meanwhile, thanks for this one!

[@AutomotiveSystem]

The fluid does leak when the system gets old, and this is one of the common problems in braking system. The brakes become inefficient due to fluid leakage. This happens when the pads and calipers are excessively worn out.

[@fgo469]

Why is the rotor different from the drum? Design wise

[@tomywoo4671]

This video was very helpful.

[@shuseikagari7927]

is that the front wheel and the back wheel or just two different types of wheels?

[@Somebody782]

[@prateekvyas6824]

which type of braking system is this? hydraulic brake?????

[@indianboys7533]

Bahut badhiya sir

[@sagarnetam6212]

it is very good for who want to know basics about brakes.

[@Blackhawker91]

Very, very nice man!

[@rezakian7460]

Hi. Excuse me. What software was this video made with?

[@L-Kammampatisaikumar]

Bro which software or application used for this animation

[@fritzkrieger3316]

What is that action called when the leading brake shoe acts like a wedge against the drum?

[@SexyAndlKnowIt]

I'm assuming you are referring to the Leading-Trailing Brake System. If the vehicle is moving forward and the driver steps on the brake pedal, the brake shoes are forced apart by the wheel cylinder. As the leading shoe makes contact with the rotating brake drum, friction forces the shoe to press harder into the drum. This occurs because the shoe pivots off the anchor plate, causing it to rotate in the same direction as the brake drum. This is called "self-energizing" action because it causes the shoe to apply more braking force than the wheel cylinder alone applies.

[@fritzkrieger3316]

thank you

[@m4nikm4ti]

Good stuff. cooling system would be cool, maybe with some thrown in contamination to show effects on components. common failures, keep up the good wrk

[@PABITRABADHUK]

why disc brake is used in front wheels and internal expanding brake in rear wheels?

[@mit4c]

ofc its better to have all wheel on disc brakes... but manufacturers put expanding brakes at the end because of the cost. expanding brake is cheaper

[@SexyAndlKnowIt]

The reason behind using disk brakes in the front and internal expanding brake (Drum brakes) is to reduce manufacturing costs thus lowering the price of the vehicle equipped with this system. In addition, during vehicle braking, weight transfer requires that the front brakes handle 60-70% of the braking, which means the rear brakes handle only 30-40% of the braking and doesn't "need" disc brakes because drum brakes will handle fine under those braking conditions.

[@pranayvalkyire2844]

why the rotor is for front one and why the drum for the rear one.?

[@Jonathandilego]

Are these drum brakes (can't be air brakes).

[@thaison9892]

Well its a little long to explain but when you apply force on the brakes, the car tends to dive forward so it requires better brake systems in the front which is disc brake. The drum brake is widely used for parking brake in most vehicles and is used in big trucks because of its cheaper cost. The disc brake is way better than drum brake for its reductional friction.

[@umangshah8971]

brakes are of different type - disc drum and air and oil are different fluid/medium by which the brake operates

[@TheRunereaper]

Your animation of the master cylinder operation is completely wrong. It shows hydraulic pressure being generated by gravity from the reservoir. The reservoir and brake lines are isolated from each other during braking, otherwise you'd overflow the reservoir.

[@daeyukim5171]

nice and easy to understand.

[@ACommenterOnYouTube]

does this work on space shuttle

[@umangshah8971]

thanks sir everythings is clear and every assumption is conformed, including the doubt after applying brakes when the flywheel and clutch qre in contact so why dosent the car move ? might be silly, but its eating my mind....

[@jayfordmallong9658]

next vid pls , how the handle brake or emergency brake works ? THANK YOU

Very Nice Thanks man

[@deoblanco9933]

Disc brake is better than expanding brake because its easy to repair and safer in floods

[@sriharshamanchukonda8448]

very nice. excellent

[@tsp8855]

but why two systems for two wheels? Why can't the car just have either the rotor - caliper combination or brake drum - piston combination?

[@muraripanem7464]

great work

[@pelms100]

Nice work , thanx

[@MaikuYT]

thank you based video. helped me alot

[@moriabelih800]

Great job you do thank you

[@paulinotou]

is there a reason why the back uses a drum and the front doesnt.

[@yungaht1429]

because drum brakes are not as effective in high speeds bro disc brakes do most of the work bro

[@AutomotiveSystem]

Thank you for your feedback...stay tuned for more presentations !!

[@qwertyasdfghjkl9604]

Lack of details. For example shoes linings are not equal/symmetrical in real systems ("leading" and "trailing" shoes are different). Self-adjusting mechanism was not addressed in the video. There are different styles/designs of the drum brakes (shoes and springs configurations).
