Perforated brake discs - Toyota Corolla, 1.6L, 2001
So, after viewing and analyzing a heap of information on the network on this topical topic, it was decided to purchase brake discs for perforation from a person recommended by friends.
On April 15, I took three sets of TRW front ventilated brake discs (aka Lucas - TRW) from a friend of mine who deals with spare parts and took them for drilling. Here and below is a photo of my kit
In time they promised to do it in a week, since this chela has the main job, and in his free time he has access to a CNC machine. He drills by patterns on any discs. Depending on the diameter, the number and location of the holes may vary. Already 4 days later they called me back and I went with Andryukha to pick up our disks. The result did not disappoint ...
A friend drilled for two Toyota 4Runner 3.5 V6 jeeps. Now the disks are being "tested" on one of them, and the person who recommended them drives these (+ also with grooves) on a Honda Accord 2.0 Chip (173 hp). Very pleased, now he also wants to drill his ass.
How will the jeep drivers respond and if they are satisfied - I can carry it to drilling, better in bulk (it's easier for me).
Drilling price 1500 rubles. for a couple of discs. A bit cheaper in bulk.
Only today, discs and pads have passed the recommended roll-in (over 500 km). In the morning I was driving from the dacha, and despite the rain I accelerated to impressive speeds. Several times it was necessary (mainly because of all kinds of VEGETABLES) to drop 80-120 kilometers per hour. Taking into account the fact that the car also acquired a new Koni Sport Kit suspension (-35 mm), the brakes proved to be worthy. With each press, a confident deceleration was felt, even from 150-170 km per hour. I will not attribute that the braking distance is now shorter, but now, when you press the brake pedal again, you do not expect the brakes to float ...
I am sure there will be NOBODIES who will overheat these discs, but I will not talk about them. With an adequate perception of reality, the brakes have the necessary reserve for emergency braking.
PS I must clarify a couple of pleasant points: the installed TRW wheels have a black factory color of the hub, which looks great and at the same time resists the formation of rust, and secondly, the pads are reinforced, which are also suitable for the RAV 4.
Price tag: 4 600 ₽ Mileage: 122 000 km
Otto are good, but the price gets out for 5 thousand, and not everywhere ... I have
already traveled 5,000 km, all normal
great idea! otherwise I was thinking of ordering Otto Zimmerman (but there is a misunderstanding about the price) ...
Mileage is about 10,000 km. All OK. After warming up the brakes, the car simply digs in. The pads are still alive, about 40-50% are left. I am satisfied.
mileage over 14,000 km. The rest of the pads is about 40% The behavior of the machine pleases!
32,000 on disks alone is worthy ... drilling on the resource did not affect in any way ... which means why pay more? =)
Mileage over 32,000 km. It's time to change. Exploited too hard. So they would have reached 50,000 km. Upon visual inspection, I found several microcracks near the perforations. I will also drill the next set of discs, I have already bought it. The master will be in Moscow after August 10, I will ask to drill holes with an offset along the radius ...
Can you please tell me, has the weight of the discs significantly decreased after drilling? or didn't you bother with the scales?
It turns out 108 holes on each disc + chamfer. With such a density of metal, the drilled piece, I think, weighs about 3-4 grams. Total 108 * 3 = 324 or 108 * 4 = 432. I think so, together with the chamfer, it turns out somewhere -0.5 kg from the disk.
I do not pretend to be absolutely true of the calculations, since I did not weigh before and after. I thought about it only after your question, thanks - next time I will definitely weigh it.
That's right, just take the disks of a decent company and trust people to drill, otherwise they will overheat when drilling and lead them, or even worse in motion. I need a machine tool with programmed control ... But now I drive ordinary ones, I miss the perforated ones. 5-6 times normal brakes "failed" from overheating. This was not the case with perforation))
Podskogi please, from simple brakes, you can do this, just nothing like this, I have not met on my slipysh, but I really want perforated brakes around!
Throw it in a personal, please, I'm thinking about drilling again. Yes, and the price tag is known?
already found a person in Moscow time who does everything and perforation and notches. if you need to take off the contacts)
Unfortunately, I couldn't even order a second set from him. The man has merged with this topic, because left work, where there was a free CNC machine (((
Unfortunately, my experience does not allow me to judge all manufacturers. But on the Opel OPC, cracks also appear on the standard perforated ones over time.
The drilling diameter is a little too large for such a number of holes, for drilling you really need to choose only high-quality discs, better than Brembo, it has been proven, does not lead them over time and microcracks do not appear. And they are also suitable for notches
And about overloads when driving a car in a turning arc. I sympathize with your experience. I will take note.
No, I turned over into a ditch twice through the roof, you can read it in my other car, well, fuck it with these overloads and all that.
My son and I traveled specifically for this purpose. He is also delighted with lateral g-forces. His child seat 0.95 G holds. And the wife on a belt dangles around the cabin)))
No. S3 until 2003 2.0 - 210 hp.
Mine in the city has time to accelerate to 190. And on the track more than 210 the speedometer sagged.
My child and I somehow dug in from 198 to 0 on the asphalt. ABS even worked. The little guy liked to hang on the seat belts for a few seconds ...
C Audi S3, which has a 2 liter engine and 300 hp? And 190 km / h on what you tumbled?
Now I go to ordinary ones - not drilled. But on the disks that are described in this part of the BZ I can say the following. I drove from the dacha to Moscow (about 60 km along the highway) in a race with the Audi S3. 10-12 times it slowed down from 190 to 80-100 km / h. Sometimes he even deliberately delayed the braking in comparison with the Audi later. Everything is good. The discs are hot, but slow. The pedal did not fall through. Now you don't drive like that: cameras around to the side of the road, speed, average speed ...
Yes, I just can say that in this case it looks cool, of course, but it must be borne in mind that even when drilling on CNC using an emulsion, this disk heated up and cooled down slowly, which leads to a change in the surface layer of the metal, which will gobble up the pads twice and at braking from high speeds to overheat faster. But now I will follow your BZ, just wondering how they will be used by you. Why didn't Brembo or TDA have a look at the finished discs? Although it seems to me this should be installed for cars with a large engine volume, but ours are so, purely for pokatushek.)))))
Yes, I just drilled. Notches are, in principle, more effective. You can only get by with them. But they shamelessly eat the pads.
And with this option, dancing with a tambourine or everything in its place without modifications?
I don’t rummage in tuning… sorry for the banal question. I'm interested in companies that are sharpened for tuning brakes ... and I'll pick up the car myself ...
kot2505RUS
Thank you, I am a supporter of the finished version ...
They also put front brakes from Kaldina, two-piston with enlarged discs
is there a link about a specific case? .. a very interesting topic for me ... although there is still a lot of time before replacement.
Here's a second DIY attempt. Soon already 15'000 km.

Is there no ready-made version from a trusted manufacturer? In order not to glue dances with a tambourine myself ...

I read this entry in my BZ. I myself have already made the following discs, the result is no worse. And in a circle
