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.
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"
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!
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.
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 ...
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!
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
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.
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.
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!
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
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.
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!
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.
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.
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....
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??
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?
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'?
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.
+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.
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.
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?
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?
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.
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.
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
+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.
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.
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?
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).

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
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..

Its very helpful to clearing out my fundamental knowledge about working of braking system.
wow what an awesome animated video! thank you guys it was very Useful! you guys should make more!
Greatly understood by the help of beautiful video and subtitles
As an automobile technology student I learned a lot, thanks
fucking liar
Thank you for your feedback Andrew! We will try to explain the servo system separately in another video.
Didn't know the caliper-piston mechanism is the same as bicycle hydraulic disc braking system. Thanks for the explanation.
Nice, just like John said. Plus nice music background too.
seeing the animation helped my understandin of brake systems

Nice explanation of breaking system of automobile
This video was very helpful.
Just to make sure that both the drum and disc brakes can be explained.
9 years later, thank you
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

Amazing stuff. Now i know how it works! Thanks a lot!
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
thanks for the great video demonstration!!!
brakes are of different type - disc drum and air and oil are different fluid/medium by which the brake operates
Excellent dude 👌
nice and easy to understand.
Very, very nice man!
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
it is very good for who want to know basics about brakes.
Good video explains alot but please answer the questions asked by viewers
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?

might be silly, but its eating my mind....
a nice evolution from the feet stopper heralded by fred flinstone
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
Very Nice Thanks man
Great job you do thank you
thank you based video. helped me alot
good animation
bt here it is not shown that how fluid get backs to its original position with this fast frequency
+Ketan Gandhi the fluid is there never leaves(if there is air bubble in fluid it wont brake properly )
When we take the leg from the pedal means automatically oil well go to the cylinder
Bahut badhiya sir
Great work dude!!!!
Thank you all for such a wonderful feedback, you can refer our autopedia to learn more about important car systems !
this video really helped me!

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

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
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.
next vid pls , how the handle brake or emergency brake works ? THANK YOU
After the break applied, how does the brake fluid goes back to the fluid reservoir?
Great video! :)
Sooo, where am I supposed to cut?
let me know when you find out
Hi
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?
which type of braking system is this?
hydraulic brake?????
great work
Are these drum brakes (can't be air brakes).
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?
Great information 👍🏻
Amazing learning.
Disc brake is better than expanding brake because its easy to repair and safer in floods
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.
Nice video
is that the front wheel and the back wheel or just two different types of wheels?
+Shūsei Kagari u got some answers to similira questions below
Very easy to learn
Why is the rotor different from the drum? Design wise
Fluid line mean oil?
does this work on space shuttle
Well explained sir
why disc brake is used in front wheels and internal expanding brake in rear wheels?
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
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.

it cames back automaticaly

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?
Good video, but I was expecting for more info's. Especially for the vacuum system which put pressure on the oil.
very helpful video
Hi. Excuse me. What software was this video made with?
Very accurate video
but why two systems for two wheels? Why can't the car just have either the rotor - caliper combination or brake drum - piston combination?
Thank you for your feedback...stay tuned for more presentations !!
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).
good job
nicely explain👍
There is not any sound. Should there be sound?
Awesome video. A good voiceover would have been fantastic.
does it have sound???
