For those who do not know metallurgy, it is an extraordinary video. It has a series of serious errors in the production of brake discs. The molding sands mixture is made as considered by the mixer, without moisture control, permeability, etc. They use cast iron from engine blocks, which is a superior gray cast iron, but it is melted at the cubilou, where they burn a lot of coal to maintain the lamellar graphite and prevent the formation of cementite. The result will be low-quality lamellar graphite cast iron brake discs. If you notice, it does not show whether they are checked dynamically or statically. A disc like this, under brutal braking, is likely to break and cause a serious accident.

I was relieved that once they started working with the molten metal they put their sandals on.

That’s crazy I didn’t expect him to literally split the engine by hand

I worked on a project in a foundry for a few weeks in the US and the guys pouring the metal had the equivalent of space suits on the entire time and 10s of thousands of dollars of PPE. Seeing these guys do it in barefeet is insane!

Представляете насколько должен быть ушатан блок цилиндров, что умельцы из соседнего гаражного сервиса не взялись за его "восстановление"?

The concern with the safety of these workers, is really impressive

14:54 отличные диски, ещё никто не возвращался с претензиями😅 good discs, no one has come back with complaints yet😅

Наглядное объяснение того, почему дорогие запчасти ходят, а самые дешевые нет. Потому что они делаются вот в таких вот условиях, из непонятно каких сплавов и какими примесями, без какого либо термоконтроля и вообще соблюдения технологии. Про рассверливания отверстий под болты вручную, я вообще молчу), на самом большом сверле видно как его бьет.

And I'll bet they could also make engine blocks from old brake rotors

I see where autozone is buying aftermarket rotors 😂😊

о, а вот и официальный поставщик сборочной линии Lada ))))

Когда мне будет казаться, что я устал, работая за компом, буду включать это видео))

Using one of the most sophisticated highly regulated pieces of steel and turning it into low quality cast iron and milling it to look like a brake disc takes some serious skill. Best part is most people don't know they're being scammed and think they're getting a real break disk when you are just getting a shiny chunk of iron.

I think I counted 10 fingers and 10 toes on everyone. Great job working safely today, team!

Я не специалист в металлообработке, но наверное отверстия под шпильки/болты стоит позиционировать относительно центрального отверстия, а не поддерживаемого в одной точке рукой трафарета. Бедность это страшно.

I really like how they all have their helmets, safety boots and goggles on. Great work☺️

man ...my back hurts just watching these guys

Теперь понятно, почему гаечный ключи made in India расходятся, когда пытаешься затянуть обычный болт на 6

official brembo factory 🤣

Страшно что этот продукт попадает на прилавки , и продаётся как оригинальная запчасти

The guy with the hammer knows every end of the day what he has done. And in the next morning he still knows it. That is a back breaking job

Когда в сервисе говорят: "Есть оригинальные диски, а есть подешевле"😂

When your buddy says "You can get them cheaper" off eBay.... 😂🤦

in theory , the engine block needs to be washed , heated , and then molded into a mold for baking blanks , for casting . and so , you will have a lot of impurities with dirt . and impurities in cast iron create voids and cavities , violating the strength of the casting .

I'm in the US. The quality of aftermarket parts here has taken a nosedive the last few years. It's frustrating to get warped rotors right out of the unlabeled white boxes they all seem to come in now. It makes sense after seeing this.

Four things I can’t get over about this: 1) how much it reminds me of Indiana Jones and the Temple of Doom 2) that they wear sandals doing this kind of work 3) that they paint the cooing fins inside and 4). That there are engine blocks they actually scrap and don’t repair.

Nice 💯 Can you please give name for each process like machining,etc so it can more helpful for us Please Thank you 👍

The discs actually look pretty good but I would not trust them on anything more than a wheelbarrow.

Голыми руками, босыми ногами, без защитных очков, спец одежды. Железные люди. Ма ша Аллах

I just love how the safety of everyone, both the workers and the customers who will eventually buy this brake discs, is the priority here. Oh, and top notch quality control as well!

Please share, what are you use for a binder in core making. Is it silica gel or something else

Those people are working very hard to Winn a bread 😓respect and salute to all of you ❤

When you don't feel like going to work, remember there are these guys doing hard work

Это конечно ужас...... Как машина будет тормозить с такими дисками? Интересно не развалятся ли они при езде по горной местности?

Impressive! Imagine having the tedious task of all. Bagging at the end 😂

Amazing street level skills...safety is definitely not on the agenda for these overworked and guaranteed underpaid workers.

Great quality control there! If the final guy goes thumbs up, it has passed.

Бетономешалка у них вообще огонь , задний мост с редуктором 👍

Putting the hashtag "cutting edge technology" on this video is a new level of humour I didn't realise was funny.

Проточка тормозного диска в чистовой размер за две установки - это мощно

И главное, это хорошо подобранный состав сплава 🤣

Guy operating a giant gas torch barefoot. Guys handling molten metal wearing sandals. Guy operating a lathe wearing a loose billowing long sleeve shirt. Nobody wearing any safety equipment or gloves while handling toxic liquids, breathing toxic particulate, and spray fumes. This video has it all!

Hats off to all those hard working people! I will not lost 5 mins in this working condition.

So what brand of brake disks are they making these for? Hope they aren’t Brembo’s, cause I just paid an arm and a leg for a new set for my X3.

5 лет назад я запасался пивом и безудержно смеялся под эти видео пакистанские, 2 года назад лишь слегка улыбался без пива, сейчас смотрю и думаю какой стартап замутить в гараже))

Not a single person of the over 1 billion total in any of these countries has heard of a work table! Amazing.

Whats the brown liquid they mix into the sand? engine oil or sugar or something?

Its amazing how these people in india can get amazing craftsmanship out of scrap with the bare minimum resourses , i saw these people making one of the best fireworks mass produced made with almost nothing but rudimentary tools , im a professional fireworks maker and can't believe what they can do with almost nothing . Amazing people with amazing capabilities for sure.

Парни настолько верят в свои станки что могут позволить себе перевернуть диск чтобы с другой стороны проточить.

As a diesel mechanic I can promise you these are rotors for a much smaller application such as a passenger car or similar. Brake rotors for semi trucks and class 8 vehicles are much larger, heavier, and typically BOLT on to a hub using 10-12 bolts. Not the little countersunk holes you see here which are typically annoying little phillips head screws.

Здравствуйте, интересно под каким название продаются эти диски

I love watching videos of people doing dangerous work with zero PPE on. Just swingin' a sledgehammer at an engine block with no safety glasses on, using a huge blow torch in bare feet, pouring molten liquid metal in nothing but sandals and spraying paint with no respirator. I love it!

I used to work here, don't let the video deceive you. we had great benefits, paid holidays, weekends off and even better employee discounts. the yearly bonuses were also very rewarding. we only worked 4hr shifts 4 days a week.

That right angle gearbox for the sand mixer made from a truck axle is slickly done. It's an old idea that works.

This is as simple as it gets to show how things are made before soficticated safety guides and machines were invented. Thanks for the videos. I would suggest the employer provide safety gloves and boots for the hardworking men.

The man is urinating casually at 3:00

Хотелось бы увидеть фирму упаковки в которой они будут продаваться

Wont the metal composition vary for different discs?

0:50 kinda looks like me at my work with people sitting around.

Те что не смогут раздолбить, заварят электродом и в машину собирать будут 🤣

А наши то токаря говорят что диск нужно на одной посадке протачивать 😅

i really hope this small company grow and make a lot of money so they can improve the working conditions for these guys and their salaries., I really y hope

Glad to see them taking all the necessary safety precautions 😢

Are work tables and conveyor belts illegal in Pakistan or what? Why after every step does the material end up back on the floor? So much wasted effort and time.

Poor guy with the sledgehammer probably has dreams about shredders at night

the disk on the lathe when he turn it over did not looked centered. do they have quality control??

Надо им подсказать если насверлить перфорацию, то ценник в два раза поднимать можно + упаковку с брендом типа brembo

Можно вечно смотреть на воду, огонь и парня с кувалдой😂

Damn.... I'll never complain about my job again.

This explains a lot of my quality concerns when I go to my local auto parts for new rotors! I thought I was watching a vid from the 1930's. Only thing that gave it away that I wasn't was the vid quality!

Definitely gives you some insight as to how powerful a thrown piston rod can be to break through the walls of an engine block!

Почему блок не восстановили? Там делов то, заварить и загильзовать, постели тоже наварить можно

Пакистан до сих пор не летает в космос только потому, что у этих ребят нет чертежа ракеты...

Probably better to make these in an assembly line with automated machines doing the work.

Good to see he's got his safety slippers on while swinging the sledge hammer at an engine block casting. 😮

Я бы купил такие диски. По любому это лучше чем китайский пластилин.

So many armchair critics, these guys work with what they have. When the shit hits the fan in WWIII, these men will survive with their uncomplicated, uncomputerized equipment and knowledge. When the light go out the rest of us will be fucked.

No scamming in a call center, just honest hard work here. I like it.

Покрасить чтобы потом ещё раз обточить, гениально!🤣

Finally, a behind the scenes tour of where Advance Auto and Auto Zone source their brake rotors!

One hammer swinger, three supervisors...efficient!

What has this world come to, some people have millions others have to work in conditions like these. Something has gone very wrong...

Каменный век. Смотреть страшно

That $39 Ebay disk rotor you bought this Summer, came from these guys.

Glad to see them take every practical safety measure to guarantee a long happy life.

Смогли освоить довольно сложное производство, но при этом не смогли сделать сдвижную дверь в печи? Приставляют кусок железа и подпирают палкой

"How off centre do you want the casting?" "YES!"

I'm an engineer not a metallurgist but there is no way I'd want to be on the road at the same time as the vehicle with these brake discs

Good thing they wearing safety sandals. (Found it in another post but still funny)

Big thumbs up to the worker @ 14:56. Nice work !

Finally we can see how ventilated rotors are made.

Is this where they built the Vtec?

Очень много тяжёлого труда! Спасибо вам работяги, вкусной еды вам побольше))) и хорошей зарплаты

It's evident that many individuals commenting negatively about these disc brakes lack an understanding of the thermal dynamics and tensile strength properties of metals. It's important to note that a significant number of American bridges and buildings were initially constructed with cast iron foundations, which have proven to withstand the test of time. While alloys have since been introduced and taken their place, we still incorporate numerous cast parts in our structures and vehicles. It's essential to recognize that the disc brake isn't solely responsible for supporting the weight of a car; rather, there are four of them on a car to facilitate stopping. To those who express their reluctance to use these disc brakes on their cars, it's worth mentioning that many of our parts already come from similar sources. It's highly likely that you're already utilizing such components, although you may not be aware of it.

i need some rotors made,how do i get in touch with these guys?

Many years ago I used to sledgehammer engine blocks, cylinder heads and other gray cast pieces, into certain sizes, because broken up cast paid more. These guys work very hard to achieve this. I have much respect for them, as well as their sore arms and shoulders, at the end of the day.

The end product had ventilation holes in the disc plates. I never saw that part where the ventilation holes were made. The mold couldn't make these holes and i saw the crude plate without ventilation holes and then all of the sudden, they were there.

Limited equipment yet very skilled workers. Great job.

You may not realize the precise selection of the metals for the crucible. They make it look easy! 😊

Интересно, а чтобы кувалдой не махать можно придумать пресс с пикой для разборки на куски?
