I would highly discourge. The thickness of break disc is an important parameter for safety and reliability. The moment disc go below minimum thickmess or significant area of contact with break pad is lost then it must be change
That would be why the spects are stamped in the hat of the rotor
There are tolerances for the thickness of discs, so long as you adhere to these it is ok to either turn or grind the disc.
There is an underlying flaw with this process (excluding minimum thickness requirements). By not installing the hub mounting surface perfectly perpendicular to the rotating axis of the lathe, there will be brake pedal pulsation.
If you watch the whole video he machines the hub mounting surface. Although that could in fact make the wheel wobble.
@@Paul_Tomlin I did watch the whole video, but the flawed logic still exists. If you watch carefully, you can see the run-out in the vented part of the disc. That's what initially caught my attention. Everything should be referenced to the hub face.
@@dirtfishingdownunder yeah I agree for the most part it's not the right thing to do but hes done it as best as possible with what he has. Personally I would just run a orbital sander with some 60grit around both sides of the disk to rough it up abit and new pads, next time will need new disks.
Id just buy new rotors like i am doing now sitting in the dealership. Fun thing is last week they sent me home missing 3 nuts on one wheel. One on another. So 4 in total. They didnt even bothwr trying to put 4 on each wheel.... i could have lost my wheel this week.
@@thomasblaine3193 In developing world, where labor is dirt cheap, resufacing might be the only option. 100-150$ for a set of discs might sound cheap to us, but could be someones entire moths or two wage.
I like the wire used as a dial indicator!
This would be impossible in Germany. The brake disc is too thin after turning and can break, which can be fatal for yourself and above all for others.
Für Optik geht es voll klar
Yeah thats why we do it here not in your country 😀
Repair for save your cost ?? ,Why not ? 😀
That is not his first time using a 4 jaw. Good set up.
But why use a 4 jaw for this, it’s just wrong!
@ Mekanik Mesin:
Great Job!
I know what or means to work without available Spareparts, so You have got my Respect!
Very good workmanship. Face all 3 surfaces in one setting. Accuracy will be dependent on machine.
By installing hub mounting surface only two surfaces need machining . In this case not only 3 surfaces but 4 surfaces must be machined.The outer surface in conduct with the wheel rim is going to run out causing wheel not running true.
@@ellastroen Agree. Last surface should not be machined with a lathe but a surface grinding machine.
If you watch what was done here, this is exactly what you should NOT do.
great work 🎯🎯, everything done right, all three important areas processed in one setting. The very clever ones can try to re-tension the brake disc and align it with the dial gauge ……. good luck ... you don't notice a few tenths of a blow on the contact surface of the rim. Greetings from Germany✌️
That rotor was junk when you started. Now it is dangerous junk.
А теперь поставь эти диски на свою машину) это надо делать на оправке я как токарь тебе это говорю с 20 -м стажем

Gday, nice job mate, just like new again, Cheers
This guy does some amazing work with very little to work with.
Hay tornos especiales para tornear o rectificar discos y tambores saludos desde 🇲🇽✌️👍
Uma beleza de trabalho.
As someone else has pointed out, there is a minimum width for disks, hence safe practice is to replace pads and discs together. All this is doing is taking the safety margin away from the disc. High chance of disintegration.
No way will that disc disintegrate.
Info according to the net
As of July 2021, the gross national income per capita in Indonesia is $3,870 .
The national highway speed limit is 80-100 km/h (50-62 mph), other roads 40-80 km/h (25-50 mph).
So, if you were driving in the city at sub 45 MPH speeds and didn't have $$$, what would you do?

Last week I changed my front brakes set, disk rotors and brake pads .
Bang, sebelum mulai, mesinny di bersihkan dl pakai kuas.
Lebih bagus klo di video
Bravo 👍
good lathework, but disc is now under size. would not be legal in Australia
Didn't see him measure thickness but it might be above the minimum thickness allowed! And as they say about the fat girl thats a very big but!
@@rcdogmanduh4440 at a quick glance, one side looked thinner than the other too

@@Yantoo I understand. You must do what you can to repair things which are expensive to replace. You did a good job! Saya mengerti. Anda harus melakukan apa yang Anda bisa untuk memperbaiki hal-hal yang mahal untuk diganti. Anda melakukan pekerjaan yang baik!
Good work. I work with a "MEUSER" lathe and a "CHEVELIER" CNC lathe. What is the brand of your lathe? Greetings from Germany.
my lathe brand is CY 6266 sir.
@@Yantoo Thanks for the answer, have a nice day!
Why use a 4 jaw, so much easier to use a face plate with a threaded screw to hold the disc against a flat face. Then you only have to machine two faces and your done, plus I bet those discs are undersize with how much was machined off 🙈🙈🙈
If is using the face plate him can't do the back side

@@ionutdanielbulai2523 you can do both faces of the disc easily when the disc is pulled up to the outer face of the smaller dia ….. done it loads of times, plus you’ve guaranteed to be true

Comparatorul este mecanic sau electronic ?
One sided turns usually vibrate due to uneven pressure on the flange of the disc, also the inside of the hub should be the mounting point of the rotor , and a rubber anti vibration band should be used to prevent vibration, this would work in a last resort , but not the professional way to do it
Would you put these discs on your vehicle?
I have had a disc shatter whilst driving and i can tell you it is extremely dangerous and causes a lot of damage. It sheared the brake caliper off the vehicle.
Mekanik suuper cool!!!
This is what you do if you can’t buy/afford new ones and they may be fine. If they’re under the limit they may warp at which point the problem will be evidenced by a shimmy when braking. Then there’ll be a trip to the salvage yard and the process will begin again.
There is a reason the brakepads don't go all the way to the edge of the disc, and that is so you can tell it's worn out. Thus you should measure the minimum thickness. Even if the disc still has a couple of millimeters left of wear, it has to be able to make it through the next set of pads without falling below the minimum value.
Although breakdiscs are expensive sometimes, they must be replaced. Tires and brakes are still a valuable lifeinsurance.
ประเทศอะไร ชื่อช่องไร ใครรู้บอกด้วย ขอบคุณครับ
Seguro q ese disco de freno está fuera de medida, y lo otro ese torno no es para ese trabajo por eso existen torno específicos para rotores de frenos, los cuales toman los rotores del eje de la masa y no por fuera como lo tomó el maestro allí. No digo q el maestro hace mal su trabajo de torno solo q esa pega es para un maestro en Frenos. Con un torno para eso. Saludos
Excellent job, but the owner need a pair of new rotors
👍
Если откинуть остаточную толщину заявленную производителем, то точнее будет точить специальным аппаратом непосредственно на колесе автомобиля. Только такая операция в сервисе не намного дешевле новых дисков
In some countries and depending on the car brand, it changes in huge amount
A disc has a reference face (not diameter) where it locates on the wheel hub. If the minimum thickness is ignored, the pads can be pushed out of the caliper housing and drop on to the road.............then you have no brakes and a disaster. The discs are gripped on the incorrect surface in this video. An accident in the making............
He can see how much he is machining off the disc's by the dial indication on the lathe's compound slide and he machined the reference face to match the two surfaces.

Sayang Vlog nya tidak disertai suara utk lebih paham.
Hei mas pekerjaan bagus lainnya. Tetap aman.
Terimakasih mas.. Salam hangat dari Indonesia
Good
Now you can drive right
I just hope you check the minimum thickness after machining?.
A friend of mine machined some badly worn discs down & had a piston pop out under breaking.
yeah that's what I thought too after he machined the rotor. It's too thin to be used the pad and the piston will pop out of the caliper
replace the thicker brake pads sir..
@@janmichaelcatap5994 I have done 100's of discs & drums in my 52yrs in engineering working lathes.
If it fails afterwards & someone is killed,the machinist can be charged with manslaughter.
in my country before use there is a vehicle test and if my job is not safe then we are not allowed to work anymore.. I was taught this kind of work by my teacher, and we have been doing this job for years. Thank God we never had a problem with our work.. maybe this way of working is wrong in western countries.. but in our country Indonesia is allowed
@@Yantoo yes we have MOT tests on vehicles every year here in the UK, but that only tests your brakes reach a certain level of brake efficiency, but not the thickness of the disc.
The last two I did I skimmed the hub faces. They were so rusty it really helped get a datum. I like the back-tool.
👏👏👏👏👏👏👏
De esa forma de centrado no q bien se coje un plato se pone en el plato bien sujeto en la parte de plato donde se coge los tornillo de le da una y ha esa parte se coge los plato ha tornea y así q bien yo tengo un torno q se monta en el coche copia toda los desviaciones q tenga la mangeta
I use to get rotors turned for $8 a piece.
I called around to get the ones on my Mom’s Kia turned, $20 a piece…. $40 to turn a set of rotors now. I bought a new set that was made in the USA for $70.
In my city this kind of work only cost 30K IDR or $2 per rotor 😀. It is cheap as hell. This is a common thing here in our country
@@richhardchoppers7869 Exactly, it use to make sense to have your rotors turned if possible, now…. you might as well buy a new set…
Ese disco ya no sirve demasiado delgada la superficie de fricción. Lo rebajaron más allá de lo normal nunca hagan eso!!
Minimum thickness what's that and that's equal on both sides not one side being thicker and the other side being paper thin
I guess minimum thickness must be about as important as hunan life if that country.
Terima kasih sebelumnya,,Mas,mau tanya,, mata bubutnya pakai merk ,atau tipe apa ,,agar bisa kuat tajam🙏🙏,,

My condolences to the driver that uses that break disc
человеческая жизнь уже стоить дешевле тормозного диска....
I did this for an e36 bmw and the results was same as a new one.
А теперь и в чермет не стыдно сдать
le comparateur du pauvre mdr xD sinon pas mal
Using a uncritical eye this looks good , unfortunately it appears he has got this all wrong, instead of trueing the disk face, when setting up the disc, He should have trued the mounting face ,where the disc is clamped to the hub with the wheel nuts ,then trued the disc faces to the mounting face , unless we he's very lucky the brake pedel will pulse
He made the back side of the hub mounting face paralell to the rotor wear surfaces and did both wear surfaces in the same chuck setup. Sure, a brake rotor lathe would be better but in a low income country, you do what you have to to get by. ( As of July 2021, the gross national income per capita in Indonesia is $3,870 )

It is better to put new brake pads on faced disc brake than on old disc, on resurfed disc brake pad can be better lapped than on old surface
@@Luminous65 Makes sense
@@Yantoo BTW:great joob.This correction is also being made here in the EU.But it's not legal and it's not done officially.I also use google translator.
I could only watch the first two minutes of the video and my blood started to boil.
I was in the motor trade for over 25 years and replaced many brake discs that had worn to their minimum prescribed thickness, some even thinner.
Only recently I replaced the front discs and pads on my brother in laws car, a Ford Focus, because the discs were knackered.
Then I replaced all four discs and pads on my brothers BMW. Why?, because they were worn the minimum specified limit
Finally I replaced the front discs and pads on my sisters Ford Ka because guess what, they were also worn to the limit.
At least I can go to bed and sleep easy, knowing that three members of my family can drive their cars on the public roads and stop safely.
It's cheaper and safer to buy new discs than to skim a knackered one.
Why are you cutting a rotor? Taking away material will only warp it faster.
We could even take the outer rim of the disc🤔
От бога 150%
Да, не дай бог!
If it is straight it won’t be the first time you hit the break pedal
💯🙏👍
If the cut takes the rotor below spec it isnt a safe rotor
Indexing worn rotor with a twig! What could go wrong?
Rotors are not that expensive, better buy a new ones. Rotor thickness is no joke.
Why use a 4 jaw lathe chuck for a round object? It makes it harder to adjust.

Não é dessa forma que se prende o disco

Anicassio, concordo que não é o melhor dos processos, mas observe que ele da um passe no fundo, onde e a referencia, da uma corrigida, nao menos este processo de torno não é o melhor também, isso diminui a vida da pastilha, o correto é retificando com o rebolo sem deixar marcas, mas é o que temos para hoje.

It's cheaper to just buy new rotors.
It is cost only $2 max $3. New rotor $100-$200. Huge diff 😀
@@richhardchoppers7869 ok so what do you do when the rotor is out of spec and cant be turned? Like I said it's better to buy new rotors.
@@oldfucker68 'IF' it is still in spec re-use it, re-turned it, re-use it again, re-turned it again untill out of spec
"Out of spec" then buy new one and REPEAT above process again and again

Why even bother, thickness is reduced and for the cost buy new, disc will mostly shatter!
Using a dial gauge is overrated anyway
