//Uniqueskill // Here's how a brake booster and master cylinder work to stop your vehicle with the press of your brake pedal.
The vacuum booster was invented in 1927 in order to provide a shorter stopping distance. Vacuum boosters provide brake assist for the driver by multiplying the force out of the booster creating more than the force that was used to push on the brake pedal. The booster works by pulling the air out of the booster chamber with a pump or other vacuum source (typically the engine's intake manifold [1]), creating a low-pressure system inside. When the driver steps on the brake pedal, the input rod on the booster is pushed in which lets atmospheric pressure into the booster. This, in turn, pushes the diaphragm toward the master cylinder.

The master cylinder is located behind the driver’s side dashboard mounted on the vacuum booster. The pressure inside of the master cylinder is created by a primary and secondary piston. These are pushed by the output rod of the vacuum booster to compress fluid within its primary and secondary chambers (hydraulic pressure). The hydraulic pressure is translated through the brake lines to the brake calipers. When the brake fluid is pushed through the brake lines, the master cylinder chambers are replenished by the reservoir (attached to the top of the master cylinder).
Brake calipers
Main article: Brake calipers
Often used in disc brakes, the brake calipers consists of one to two hollow aluminum or chrome-plated steel pistons (caliper pistons). Brake calipers are one of the most important parts of a vehicle and are essential for your car's ability to stop. The job of the caliper is to slow the car's wheels using the friction they create with metal disks (rotors). They work by taking the pressure given by the master cylinder to force the pistons against the rotor. The development and use of disc-type brakes began in England in the 1890s. The first caliper-type automobile disc brake was patented by Frederick William Lanchester in his Birmingham factory in 1902. In a disc-braking system the rotors are attached to the car's wheels and spin together.

Main article: Drum brake
Another type of power brake installed in automobiles is called the drum brake. This type of brake, in general, will create some friction that will slow down the wheel. How this works is there is a brake cylinder that connects master cylinder to the drum brake via brake lines that transfer pressure from the master cylinder. When the driver pushes the brake pedal with his/her foot, the pistons inside the cylinder will activate. The activation of this piston will allow two brake shoes located within the drum of the brake to expand, thus generating friction to slow down and stop the wheel. Usually, this brake is located in the rear wheels of the vehicle, while the disk brake is located at the front of the vehicle. A car may also have only drum brakes or disc brakes both front and rear.

I think I'm lucky to have been watching this video, it saves me from8 year's stress of my ford brake booster nearly bought new one.
You guys are champions, everyone here says don't do this, it requires special tools or it's too difficult just buy a new one for some incredibly outrageous price. I'm inspired and going out right now and taking mine apart. Mahalo Nui
Updating for you, I did it! Took it apart and quickly saw the failure and was able to gently manipulate it back to it's seated position. A little more tricky putting it back together then you make it look, guess that's an experience thing. Patience and confidence gained from your video got me there. Thanks so much guys you saved me $300 USD. and more importantly I gained another ability making one less thing that I have to rely on some greedy corporate slim for and that's priceless. 🤙
Is that still working fine?
Thanks for sharing your experience.
Should be dry inside. Most likely the Master Cylinder (MC) piston leaked to suck brake fluid into the vacuum booster. That is for those thin pancake-body booster where an O-ring seals vacuum between MC and booster. Thicker boosters, like in older cars (I've seen in even late 1990's Chrysler cars) have a bellows seal at the output so any MC leak will drip out before the booster (usually a drain hole). I think he is just washing the parts in water, since glycol brake fluid (DOT 3, 4, 5.1) is miscible. People say the glycol fluid can damage the booster rubber parts. If you use silicone fluid (DOT 5), I doubt any damage since benign to rubbers. Hardest part in rebuilding a booster is sourcing new parts like the rubber diaphragm. This one is a Bendix style with a crimped cover. Midland-Ross are easier to disassemble since use a V-band clamp to secure the two shells.

Похоже, что ВУТ должен был провернуться для разборки, как волговский. А они завандалили зубилом.

Thanks for visiting
Gran trabajo. Ya no existen personas que tengan el conocimiento y la paciencia para realizarlo. Ahora en todos los talleres solamente saben pedir piezas nuevas.....
In my experience, no worries if you repair the booster as long as you made it perfectly because our public utility vehicle runs for couple of year without any problem with the break. But yes safety is a must and you think the break booster is hopeless to be repaired then buy new one
Yo admiro El travajo de Ellos pero hay un problema muchas personas en Este pais no pueden remplasar estas partes para Ellos es muy caras claro es un circulo trabajos para unos ayuda y ahorro para El cliente.
Service boster rem...wow..amazing..watching from indonesia
Very talented I watch these guys work on ground. Take time build bench it’s much easier to work on it
Mantap hadir nyimak kawan dan sukses selalu buat sobat 🙏🙏👍👍
Excellent video. Simple, straightforward, clear, comprehensive, honest. Let's hear it for the camera man, too.
You people got very nice skills..
Your tough mechanic but avoiding wash petrol on rubber of highdro rubber expand become weak
Very good job all around; thanks for posting !!
Pakistani mechanic are the best for repairing the used parts .As every one can't afford to buy a new one it's quite expensive now keeping the currency devaluation.
This is a good way to restore old things!
Ordinary grease is the enemy of rubber oil seal!
you are Right Brother
Silicone grease?

Just use cooking vegetable oil, it works well and will not crack the rubber seals.
Reuse and recycle reduces so much junk on the planet. Repairing should definitely be done where possible.
Verdaderamente ustedes si saben mucho 👏👏👏👏👏👏👏👏👏👏👏👏👏💯

Nice, repair, keep up.. this idea is quite useful. Pocket saver.
Yes, thanks
It’s amazing he didn’t get any of that solvent on his feet while cleaning the assorted parts😳

yours skill very good
Top video briliant 👍
Thanks you. Good job
With all that brake fluid in the booster, you're gonna also need a new brake master cylinder.

Luar biasa mantap
At least it shows what is inside it
Food job . Some cars break system is so hared repair it . 👍🏼
ماشاء الله
Worked very fast
Who says you need fancy tools and a shop. When you can do it on the ground with feet out.
nice
Это ввостановление агрегатов после авторазбора?
And where is the repair? They just cleaned it very well:))

They put the old seals back in. Why rebuild it at all?
Merica!
Toyota? or what car is that for?you replaced the retainer seal center only
Very nice
Innova ka bhi hoga kya repear

Where did you get the repair kit?
What repair kit? They reused everything in the video. And only used a sludge hammer and flat head for the most.
Where is this work shop located?

Hope it works after all this effort 😅
Yes it will
Thanks For Watching
Это не ремонт , это разборка и чистка от масла погнанного вакуумным насосом , в принципе не сложная задача относительно и если нет возможности купить новый или бу .
Возможно это тормозная жидкость которая поперла через главный тормозной цилиндр.
@@garikdez согласен , может быть и тормозная жидкость , правда тогда нужен ремкомплект главного тормозного , а на видео вообще не понятно меняли ли что-то или просто пересобрали .
Вообще не очень понял. Если мембрана целая, он должен был нормально работать, и чего его тогда курочить. А если не работал, то смысл в переборке без замены деталей?
Pasen el dato que fue lo que repararon.? No se vio nada solo limpieza. Tal vez due otra falla que lleno el sistema de aceite. Y si era aceite eso daña el hule
Much better to buy original surplus or brand new.
Kha ka h ye
I need that rubber
Vacum Booster bosgu
In smaller cars th-cam.com/users/postUgkxSRYZLHOTuxMO1hZD5z_fteeFGLKsBP5i it is a little wide and kind of difficult to reach the seat belt buckle in the car where the booster seat kind of covers it. But overall, it's great. The cup holders fold in if you want. My granddaughter loves it and is so excited to have outgrown her car seat. I am constantly reminded that she now has a booster seat, not a car seat. Will probably buy another for a different vehicle.

You will notice once you step on the brake, if it is working or not.
I think so. I think there will be a hissing sound.

Nary a new part anywhere. All we did was clean it in gas. That alone scares me
the question is how long will that manually refurbished brake booster last??? And its quite dangerous if that brake booster break down while using it on the road!!!
That will never happen
@@uniqueskill96 why is that so? because you changed a new rubber seal??
Thats true! Much better to buy a original surplus or brand new, than repair it!
@@yojvilleza8167 This days, almost everything is remanufactured. That's what. they doing.
If your booster stops working it just means you press harder to make the brakes work, that’s what the booster does, uses the vacuum provided by the engine hose connection to help suck that pedal in easier, and they rarely just suddenly fail.
А почему его просто раскрутить нельзя? Зачем портить геометрию корпуса?
Возможно потому что он не раскручивается
@@garikdez я свой раскручивал, после того как мембрана порвалась, и ремонтировал спомощью ремкомплект а у меня газ3110
@@user-ll2kz6gc2m на вазах и москвичах похоже надо курочить, как и тут в видео.
No repair amything here. They only clean the boster.
Yes all they did was pull it apart clean it and put it together with the old parts they washed the rubber diaphragm in petrol it will swell up and go really soft
The only thing wrong with was the fact that it had fluid in it from a bad master cylinder. They cleaned it and put it back together. But no repairs on the booster it self
Так вот оно какое производство ВУТ на ладу гранту /весту и ладу рентгеновские лучи. 🤣🤣🤣🤣
This was not a rebuild. One must use a new overhaul kit to rebuild a booster correctly. What this guy did was just cleaning the booster. He didn't replace the seals or anything.
Also, never wash rubber parts in petrol. That diaphragm wont last long after its nice long soak in that refreshing bath of petrol.
Cleanup is certainly not something they were brought up to do, if it was in Denmark, the oil was allowed to flow on the ground, then there were fines, what the hell is it like to be so indifferent to the environment.
Pakistani guys!
Here in Italy too, if you flush oil (any kind) on the ground, you can have your workshop shut down!

How to destroy a brake booster.
In the west 'mechanics' really are just parts replacers who overcharge you. Over there mechanics are actually mechanics. I have no idea how much these guys charge for fixing that brake booster, but I imagine it ain't much.
I'm a former tech of many machines (5k repaired), do my own automotive work & dropped out of a manufacturing program. Replacing parts often makes more sense in the long run. Especially something relatively cheap with rubber parts in it like a brake booster. I bought a new master cylinder (40 dollars) & new brake booster (75 dollars) for my own vehicle because the remanufactured units were the same price. Some things should NOT be rebuilt.
Unless you mining and forging ore and materials into the end product, you are a "Replacer". Its at what level you want to stop the process of FIXING and just replace.
4 or 5 dollars repairing charges
