Subscribe for new videos every Wednesday! - goo.gl/VZstk7
Porsche Surface Coated Brakes have a thin layer of tungsten carbide on the outside of the rotor. This tungsten carbide layer means no rust, significantly less brake dust, and they don't have brake fade typical of cast-iron brake rotors. The tungsten carbide layer is applied using high velocity oxygen fuel spray, and provides a rotor that lasts about 30% longer than traditional iron rotors. Better performance comes at a price, but they're about 1/3 the cost of carbon ceramic rotors. These PSCB rotors come standard on the Porsche Cayenne Turbo and Cayenne Coupe Turbo. Check out the video to learn all about Porsche's world-first brakes!

“Engineers have no feelings, so no feelings were hurt.” Truest statement ever uttered!!!
As an engineer I can assure you there are plenty of bad engineers and scientists. Don't trust them all.
Tell that to the prima donnas at my work places lol
@humandxp nope. Empathy is the logical conclusion to a mental equation that replaces x=them with x=me
Not only that. You will be amazed at the responses you'll get returned. If you wanna get ripped a new one, go argue with an engineer! Aussie engineering school was honestly one of the most hilarious experiences of my life!
@@THEGAMINGHELP101 As an engineer, I totally agree
Loved the "They didn't realize engineers don't have feelings" line. I once took a psych class titled "Introduction to Personality." The professor was getting frustrated because this particular class was very quiet and not really responsive. From the front of the class he said, "Come on! Let your personalities show!" I slowly raised my hand and glanced around nervously, but.. when he called on me I said, "We're engineers, sir. We're here to learn what personality is."
👑👑👑😂😂😂
Yes.
Underrated comment 😅
Engineers have a personality. The stable personality.
@rosomak8244 "He's right you know"
Now I know why people with Porsche never brake in traffic, it is too expensive.
Braking is not fuel efficient. I hate it, it contradicts my goal of getting somewhere fast
It's because they don't need to slow down for turns and you need to get out of the left lane.
@stijnvandamme76 EXACTLY 😂😂😂
The other way around....No they ride the brakes because they have too much power for civilian roads, and the aged owners get scared that the vehicle is moving too fast. These cars' potentials are wasted on most of the owners.

@@nicholaslau3194 ah finally... Now I understand what brake-fade actually is then!
@@EngineeringExplained I want to see a video explaining wether or not whiteboard brakes are possible and if they are possible how good would they be, yall agree?
When I worked at a Jaguar dealer, we had a customer that tracks his F-type, for fun not competitively. He changed his pads and rotors 3 times due to wearing them down on track in just a few years... they were carbon ceramic brakes, and surprisingly they're the same price as Porsche's! he basically paid for the car again, but this time just in brakes. I think it would be cheaper to take a hit on depreciation and just trade in the car for a new one than to replace carbon ceramic brakes
@420 Friendly they are more concerned with selling new cars than worrying about repair of used cars, they also would not be paying that price for the repair anyways.
Lol
@420 Friendly I wasn't in sales, reasons unknown to me, we check the cars for maintenance stuff after buying them, the used car dept pays for brakes/tires all the time.
@@stephensheppard3501 we do pay close to that actually, the mechanics still get paid the same amount, and our cost was only like 2k less than retail
Due to that, some owners swap the pads to steel and then reinstall the original pads when it is time to sell the vehicle.

“That’s a level of baller I cannot comprehend” 💀💀
Hah, yeah, I liked that one too :D
This technology was used on bicycle rims for many years by a company called Rigida (renamed to Ryde). Their rims were called CSS (Cardbide SuperSonic - indicating the processes by which the tungsten carbide was applied to the aluminium rims. The wear rate was very low and the rims lasted much longer than normal aluminium rims. They did however suffer from brake squeal and somewhat inconsistent wet weather performance.
And nobody bought them because the performance and cost surpassed the need.
Great example and quite funny, Thank you for sharing.
"70% of brake dust actually comes from the rotors"
I never would've guess that, I always assumed it was just the pads!
Also, the best part about those price breakdowns, it that in 20 years when the Cayenne Turbo is worth like $10000 on the used market, the brakes will still cost $11000 to replace with OEM parts
makes no sense that 70% would be from the rotors, the data showed was 1500x the wear on pads vs. rotors on thickness, the rotors are no where near 1500x the area of the pads
Porsche says that. But his own data says pads wear 1500x greater than rotors, and dust comes from pads. Anyone knows dust difference between organic and semi metallic pads is huge.
Also Porsche owners rarely buy their cars, they rent them, so they don't care about resale or any wear beyond 36-48 months.
Yes, if the pads wear 1500x the speed of the rotor, that's 1500 good reasons to expect the brake dust to be mainly pad
@@truantray I think y'all misunderstood EE, that "1500x" metric is specifically about the tungsten carbide rotors and the pads designed for them. Typical rotors are cast iron and the pads eat away at them significantly faster.
Metallic pads actually produce more dust because they remove more material from the rotors, which is a byproduct of the increased braking performance.
@@Balomis the 1500x was for iron rotors
Those carbon ceramics cost more than my whole car to change.
32k could put you into a decent used Porsche too!
Same haha, more than my Crosstrek or my MX-5 new, or both of them combined at present value. 😳
Honey my brakes are squealing!
Don't worry babe, just go down to the dealer and pick a new one out!
And not a crappy car either!
Brendan Yup, you can get a 2015 macan for 20k
Reaching 100.000km on my 2018 Porsche Cayenne S equipped with those PCBS brakes from factory and they still look like new (even with a lot of towing 2.2 tons). Disks look like new, brake pads are at approx 50%. I really like this technology
Lotus used Metal Matrix Composite (MMX) material for the brake disks on the 96' Elise. Mixing silica carbide into the aluminum gave the same hard surface. No wear, no dust, and excellent braking performance. The pad material attached itself to the rotor surface (a few micrometer thick), giving maximum adhesion friction, which you get if you have the same material on both surfaces. Material is constantly transferred between the disk and the pad back and forth during braking, resulting in the low wear of both pad and disk. The weight was as for aluminum, so very light compared to cast iron, reducing un-sprung mass. Aluminum conducts heat much better than cast iron and transfer the heat from the disk to the larger wheel mass and area. So temperature was about half of that for cast iron disks. Downsides were high production cost, and eventually metal fatigue issues from uneven thermal expansion of the different thickness of the boss and rotor when using such a hard and brittle material. Surface coating seems cheaper and better, except for the much higher mass of the brake disk with cast iron as base.
Came to the comments just looking for someone to mention Lotus MMC brakes. Thank you!
Cost is inversely proportional to dust.
Better use that regen in the Taycan or you're gonna pay
Give me brake dust, at least then I can see where my money is going.
No. Just look at ATE ceramic pads. Affordable and almost dust free.

Exactly. A good, reliable car doesnt have to cost much. Everything beyond "just doing its job" is pure luxury honestly.

@@JS-nt3cn 4x2k is still less than 30k.

I had a friend who owned a 928 back in the late 80s. He said "it's an amazing car to own for 6 months. He said that was about as long as you could afford to drive it before the maintenance costs would bankrupt you or you'd have to sell it so cheap that it would be a nearly total write-off. So nothing has really changed.

Brilliant - I love your character, demeanor and presentation, so professional in a concise and intelligible format (and of course interesting).
So for carbon ceramic brakes, the replacement parts cost half of the price of a standard Porsche Cayenne, the car where the brake sits on. It is more cost effective to buy a brand new Cayenne and sell your old one than replacing the brakes.
This is literally the printer model of business. Implying that the car is somehow disposable
Saurabh Kulkarni
That’s exactly what they are planning
any car in parts is stupidly expensive... a couple years ago I read an article in a car magazine that did the math on how much a complete car would cost in replacement parts. They used the most sold car in my country, Germany, the VW Golf:
a well equipped VW Golf from the dealer, costs about 30,000€
the same Golf in OEM replacement parts (no labor) costs over 250,000€
now you know where the real money is made...
@@cedricfranzen8558 Seems interesting .... but it s a LOOOT OF MONEY (i was expecting like 100-150l). Anyway - did you find the article or something similar on the internet ?

Imagine buying a 2nd hand Cayenne in 10 years for $32k and the dealer says the brakes need replacement...
for another 32k lmao

This could be used in electric cars. Since they practically don’t brake at all using brakes, but instead use recuperation, the rotor becomes very worn due to rust. So then when you do need to slam on the brakes, you find that they don’t actually work.
I've been driving electric cars for 10 years and rusty rotors have not been a problem for me.
The Taycan Turbo has these coated brakes as standard.
Who drives their Prius at 200mph and then worries about brake rust and brake shudder? Electric cars are the same category as every other car - almost nobody drives them that hard.
@@shawn576 taycan, Audi GT, plaid...
I agree. I recently drove an EV owned by a relative who almost never touches the brake pedal (he uses strong regenerative braking and tries to drive "one pedal" almost entirely), and even though the car is driven daily the rotors were clearly rusty - I could feel the grinding when I used the brake pedal.
Great job on the video. I found it to be really informative and my favorite point was when you did the price comparison. I wasn't expecting that at all! Don't worry about the comments, there are haters everywhere on the internet. Thanks for the info!

@@Theart0fstyle I'm not sure what you think 90% of people drive, but it's a solid bet that it doesn't take 5 years of depreciation before they're worth less than $32k.

No way now - not even if I’m pulling a caravan. I’ll just use the gears and the regen function with braking (which should save the brakes anyway!).
Great work!
The advantage of ceramic coated rotors in a hybrid would be reduction in rusting of the lightly-used rotors. With any luck, they'll last as long as you keep the vehicle so the replacement cost would not be a concern.
Really cool way you record the video! Thank and keep it up!
... And you probably can't change them yourself, because it would require dropping the engine and transmission and then extracting the rotors from the top of the strut mount through the exhaust manifold (which requires a special tool that only Porsche dealerships have).

@freezeme360 "it's just a condom , slip it on " this is what ur mom said the night u were conceived
I guess some people here have never worked on a car. You made me laugh. As a mechanical engineer I have wanted to throttle the person that designed some of the junk on cars. I mean really, why is the fuel tank access port on top, where you have to drop the tank to get in it. I am pretty sure we have the ability to seal one placed on the side or bottom where it would take seconds to access. Or perhaps having to remove the exhuast system to replace an O2 sensor. Or remove the entire engine to replace an alternator, distributor, or AC compressor. The list goes on...
@@court2379 The access port for the fuel tank is on the top, so that you can access it regardless of how much fuel is in it.
O2 Sensors mounted vertically can get too hot and if they are mounted from the bottom, condensation can collect inside of them, causing misreadings and failures.

Me deciding if I should splurge and get $150 "racing" brake pads
Porsche- $32,000 take it or leave it
Not unless you’re racing... For street use the racing type are worse (like ceramic won’t work well until it’s hot, and bare metallic pads are really loud screeching and destroy rotors fast), so the best ones for regular street driving are the normal semi-metallic and maybe even some organic ones (but the organic ones are often worse). So unless you want poor breaking normally or screeching to the point your ears want to bleed then I wouldn’t suggest it.

We often use HVOF applied carbide for guiding surfaces in high temperature (above 600°C) applications. The surface is so hard that only grinding can be used for machining it - and even that is not ideal.
@11:50 I was waiting for you to casually kick the rim under the sill for the 4th safety :D
Having watched your videos right from your first year over here, helped me with my automotive engineering big time.
Looking your channel grow to this scale after my education is done makes me very happy.
Best of luck for the future!
Those prices are insane. You can buy an e36 M3 for the replacement price of these fancy porsche coated brakes.
But why would you want a 25 year old car? 😉
Even the regular iron rotors cost as much as a 325. If the price of the iron brakes is anything to go off of then all of those are marked up about 10x from what they should actually be.
A prime example at that!
Why are people complaining about the price of an exclusive brand ? It's supposed to be exclusive.
@@scratchy996 WTF is exclusive about Porsche? Every overpaid professional is leasing one.
Such a great job done !!!!
Great presentation as always.

made my day
I am an auto enthusiast from interior of Brazil and I use to study mechanical engeneering before I change to music education. I really love your Channel and aways see your vídeos as renewing my point of view. Thanks a Lot. Keep UP the Very good work you are doing.
"...changed to music education". And another one gone, and another one gone, another one bites the dust! R.I.P
The replacement cost on those brakes is laughable! The ones that it come with from the factory are 7.5% of the cost of the entire vehicle, that's crazy! PS great video!
I’m a fan.... because talented people with incredible communication skills surpasses most educated engineering.
Great ... almost always the best technical explanations available. Thank you keep up your fantastic work. BTW just ignore stupidity.
When the "track day" is a whole family event...
Hahaha, love it!
...And have you seen those races where everyone's pulling a trailer? Good times!
Hahaha, all talking about Porsche while wearing a McLaren cap, nice trolling 🤣
Haha, it's subtle. But the internet always notices! ;)
