Dead groove brake discs + notches
Often it happens that the brake discs come in a state of disrepair due to operating conditions, and the thickness is not worn out. And often buying new disks results in a lot of money (about cheap China I'm not saying their not long enough, according to statistics). And in such cases it helps to groove the discs.
Here is a small illustration.
The rear discs from the GT-S. Spent
In General, it is clear that they are not very good. We bored through and struck notches. The shape and the hemispherical profile of the notches is completely copied from the EBC-USR-Series. Stock thickness, there is still very big within the denomination. Wheels on the edge of tolerance we don't back up.
Also did the front rotors 332mm Proma. Native notches were erased to the ground, which somehow involves the replacement of the rotor, according to INDU. Although various manuals resource has not been developed.
Bored through and cut.
That's so cheap and cheerful, but like new. Auschott Motors in da house.
The price of a new rotor industrial is generally far incompatible with this update. So the profit.
More often have to treat almost new wheels. Here is an example of the disk thickness as new, but as not so good. Started strong grooved disk wear (after slides coy who painted directly on the machine Bay and still drive a thermal point of the soul).

Full sizeAnd here is the result after cutting. Took a little less than 0.1 mm.
Full sizeThe thickness is 28mm new, 26mm tolerance. Draw your own conclusions (this is the word for those who thinks that the groove cut "a few millimeters of the surface")

if much to whittle away the disc the Shoe can fly out of the caliper at all) we had such.
enough of a difference to 5cm
the groove gives the effect of the NEW disk. the only difference is the thickness of the disk and we remove just a little bit.

the price of a single disc 9000R. And the same resultat on BU original disk. 6 is a multiple of the difference in price for the same result actually. Believe me the Celica owners are not so rich to pay 18,000 rubles for 2 disc vmetso to continue the same to over 3.000 p. So your offer is simply not competitive
I don't think that turning straight has the same effect as brand new drives.
although the ultimate cheap and cheerful) I think the braking distance in both cases will be the same

easy! no difference at all whatsoever. my rotor 316мм slow in any scenario better flow which you offer
just kidding)
Well, Yes, composite 316мм Proma rotors with aluminum hub — drain. And TRD (normal neoriginal logo TRD) is the tuning. Pash, without comment.
easy! no difference at all whatsoever. my rotor 316мм slow in any scenario better flow which you offer
uncles. I have 3000 p is a groove with notches for a COUPLE drives. Understand and you have a PAIR just like 15.000 R! the obvious choice of the majority.
to pierce of course cheaper, but the notches do not. someone beauty takes)
there are notches and perforations, more expensive.
there are options just with perforation

5 fold difference. I think at least one person will overpay for Stoke a couple of CD's? Is the price of the swap kit for 4-piston brakes from the GT FOUR. so...
+ stoptech more durable and durable than stock. although the life of the disc brake pads depends end from too.
it's not Stoke, it's "Ala Stoke", but Stoptech actually makes the TRD for all)) i.e. count 15 you take the TRD, which is pretty cool. + they are with notches and the drain is not)

Common), many complain about the beating after the groove.on this and ask exactly how they would furbish
it's about turning on the auto! on the machine is another story
Yet no one complained. Conclusion? sharpen normally.
What parameters of the process are you interested in?

the deadness of the disk is determined by the manual. The option is called "allowable thickness of the rotor". We sharpen literally dozens, and there is very very to the limit values. In General, not talking about boring dead in the trash drives where you just don't have thickness.
somewhere I saw that it is dangerous to sharpen dead disks, because the rest is minimal and the incisions deeper, people disks are burst in places cuts. something like this x)
how much is here and so protocals?) and make incisions ? 4 drive 34 sky turbo the brakes
Depends on how dead the brake disc. Some even do not presume if there in the trash and wear to the limit. Protecive depending on what is initially state, such as deep grooves. So everything individually.
The plant is done when the product is already cast and processed. that is, in the final stages
Work perfectly!
Only I have a question, you may know the plant as make the perforation and groove, not at the stage of casting is immediately formed, or later on the machine, too, face piercing holes?
Yes, I understand)))we have the machine is just 50 year.there is a paddle instead of NC))))
milling machine may be a CNC without CNC) on what to do such a job is not important, agree
How much it will cost to make a dent in the front of the new ATA (not ceramic) Discs still in boxes.
Of course, in the absence of cons, have a number of important advantages. They are all more or less evil machines already in stock, and about tuning brakes I am silent. Therefore, to do or not to do is solely your choice.
our — no. Selection of inexpensive substitutes for extensive. But it often happens that the disk is expensive, but because of the cheap pads bad it was covered in deep grooves, while the resource thickness is still far far from being exhausted. At a fraction of the cost of the groove, comparable to a new drive get the same result — a new surface.
And the application of cuts will reduce to a minimum the wear of the grooved disk.
does it make sense to eat through brake rotors at relatively high prices? or so it is worth to bother only on expensive CDs?
If the drive itself is worth it to him to do it (great balance and General condition) then Yes.
Wow great, and how much will cost the application of cuts on the new wheels? A perforation is also possible?
No. drive admission even after the groove. Crack can not, this is Japan, not avtotaz.
and unless the discs in the photo were not from great wear, even for the photo bend wear more than 1 mm on one side. But from this treatment, regular drives not designed for this kind of cuts can't crack?
Yeah)) 2mm groove saw))) This is FUNNY! you obviously never held in the hands of these discs, measuring tools, and certainly with his own hands didn't do anything. How can you then criticize? This disk is now on the client machine which is in my box. There to edge topsala runs and drive, uncle) so chill out
you yourself are nonsense, the photo shows furrow nearly 2 mm depth and just very natural from the generation of Kant, on which 0.1 mm is it?))) Disgusting to hear this "professional" Nonsense
Do not think that you are smarter than others, that's stupid. If the new disc thickness is 28mm, tolerance to 26, and off I BU 0.1 mm, and it becomes like new, only 27.5 for example... no comment. The theory you know. When the hands on the machines to work, learn and then talk
that's just recapctha, groove of the disc is for the rogue who can not support your car, many manufacturers give no more than 2mm wear, and then a replacement, those same Japanese discs no sharpening, but only grind a small does not flatness if you allow a margin of safety
I'm laughing with you)))) I Read your BZ)) and EW rzhu) Quote:
"Incidentally, who's to say the oil is checked when zaglushina the motor in the automatic transmission?"
I whom I argue...
Comment has been deleted
not that I would advise people to sharpen discs and allow to cash in on them, so Woe to the masters like you
First, you are in my theme ... and while I'm here shit you be so kind as to listen to.
Secondly, you are deceiving the opposite side rubs the carrot.
Third fastest grinding occurs due to the lack of grooves (they make grinding new brake pads very long).
On the second question. Do not consider yourself so the most intelligent thing you've found something that we do not know and do not take into account in their work. Something is not pleasant — pass by. Useless to argue any technically sound argument can not lead. The mere statement that the notches neigh pads like a cheese grater is already an indicator of your knowledge.
Vasya Ivanov from the Tula region has a rich knowledge of braking systems, and stopped for the belt all the scientific research Corporation EBC.
I wish you success and realization of your projects.
First, nobody has rogovaia(Not culturally fit in a conversation between two people) In the second I just rubbed a whole plate of carrots about the back side of the grater. Now with sugar eat it)
And thirdly, since you have so they held up the bunch, then tell me please which significantly reduce time required for grinding the next set of pads already podkatom drive? Isn't the effect of the floats?
And the second question. Once the groove is a wear indicator disk — erased notches — ROM worked its nominal thickness, then what do you gaffe bored through already worn disks?
But in the end, this disc gives an advantage only when used with a pad that compensates for its reduced surface area. This is for you to help "technically competent "interlocutor)
It is not necessary to write is not verified information, right? Why flaunt my technical ignorance. Open your books and find out what is cutting edge. But if there is a problem with the perception of information then just take a grater for carrots and try to cut even a millimeter of carrots about the back side of the float (when the edge of the inside look). Nothing happened? That's it. Also, with the notches, they have no cutting edge as such, so when all desired notches can't scuff pad. I have one set of brake pads in 3 years ate discs with notches with the new state to the edge of the denomination and choked. So draw your own conclusions.

sorry for the question, what do the notches?
Wash pads in the trash(like grated carrots)
Well damn you on the Subar ' apparently very vigorously go) I rarely fry on the selikon so that the pads are spent so quickly.
Weird. and that the model was Suportul and discs? I have the prom 4 piston disc 316. 25.000 km in the PM track.
Well XS. I pad enough for ~12ткм of the city, WITHOUT track and pokatuh. Disks have fallen by 50%
I have Yellow went almost 3 seasons and the creaking was only the first 1000km while we have adjusted, then yellow continuously regardless of disks. One set of brake pads ate new drive completely.

Key benefits:
1) prevent the formation of grooves on the disc, which are inevitably formed during the life of the blade without notches
2) increasing the life of the pads and disc
3) drastically reduce time required for grinding the next set of pads already podkatom disk
4) effectively disperse the products of wear pads disc from the contact patch
5) looks nice
6) is an indicator of the disk wear — worn notches — ROM worked at a nominal thickness
7) is Reduced to a minimum the likelihood of difficulty even for poor-quality pads
This is all information from the EBC and I'm inclined to trust their research. And the facts of my experience of the use of the notches is confirmed.
Do not believe them))
Yellow stuff crunch in the USR drives, but closer to the death of the pads
About the effectiveness can not say — is a parameter which depends entirely on the state Suportul themselves pads and rubber. But in General, Yes — this is a very useful revision of the new disk.
we can conclude like this, buy the usual brake discs and machined? and +we have a small increase in braking performance?)

If there is significant disk we is not recoverable. BU discs sharpen only in the case of minor light wear. It is required for applying cuts on the BU disk in any case.
I read your entry about brake mechanisms. If that's all you know about them it becomes clear the meaning of your post.
Thanks for the opinion, however, we do not agree because of the experience in this direction.
Essential grooves, the ribs and the more "belly" and "cone" of any will have a thickness of not less than millimeters. Millimeter on each side — this is two millimeters (allowable development and many drives = 1.5 mm).
If the above mentioned surface defects less than a millimeter, they are not what really affect and turning does not make sense.
I believe that our drives only if they had warped and there was lateral runout (if the thickness allows you to pierce).
Hello! How much to pierce the brake discs in 3 planes? And where geographically? Thank you.
Welcome!
How much will it cost to pierce and cause the notches on the discs promosie 332х30?
Quite a possible, and allowed adequate recovery disks! I myself revived: www.drive2.ru/l/3399502/. Great chase!)
we have hundreds of completed orders drives the percentage of school — 0. just any Turner will do if you do not specialize exactly on brake systems.
Competently, effectively, beautifully. Well done! And it does not cut carrots on automatic transmission with stalled motor, and then people say sedet they have there in the field somewhere)))
Is it worth it to eat through the disc thickness 20.5 mm, if the maximum wear is 20 mm?
Got from the last owner, the balance is decent and staff is good for track, but the border of the slag remains on the edge, new pads bad priderutsya
