Porsche Reinvents The Brake Rotor - No Rust, Low Dust, No Fade!

Porsche Surface Coated Brakes (PSCB) are a brilliant new brake technology.
Recommended Books & Car Products - amzn.to/2BrekJm
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.

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

[@jimscimonetti1457]

Your videos are amazing. Thank you so much for making them. I appreciate your work and the way you explain this stuff.

[@Balomis]

"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

[@fuzzy1dk]

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

[@truantray]

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.

[@CED99]

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

[@Balomis]

@@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.

[@dagandrefjeldstad3856]

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.

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...

So, 30% longer wear life, 500% higher replacement cost. Sounds about right.

[@taekwondotime]

This is how Porsche makes their money. They KNOW Porsche buyers will have to have it for their car and will upgrade to it immediately when they release it.

[@syproful]

You don’t own a Porsche just move yourself. You own it to enjoy yourself. And relieving someone from the burden that money can be. Is also enjoyment to some.

I've seen other famous KZbinrs who've let their family members raise a truck on just a jack and then their nephew is sitting under the rear suspension, working on it. If that jack fails, his legs would be crushed and his whole life would change. But they're also cavalier about safety in other respects as well, such as not wearing eye protection while grinding or drilling, not wearing seatbelts while driving on the open road, etc. You did just fine suspending the car for a photo shoot, and until you pointed out the hidden jack stand under the floor jack, I hadn't noticed it and I still wasn't concerned. And since you don't have feelings, then a sarcastic response to the haters out there shouldn't affect them, either. But nope, you kept it all above board and showed who's the bigger person. Kudos!

[@glennaguon5165]

When you buy any exotic car. Whether that’s Porsche or not. You don’t look at the price of the parts. You’ll be looking at other costs. Hell you’ll probably trade it in for a new one in a few years. You’ll be making enough to cover the cost of it in about a day or less.

As a mechanic, I can say thats the best option. It isnt very fun to tell the customer who ran over a stick and some air deflector that can be made of plastic and mounted with a ziptie, would cost 100 bucks to replace because its some fancy piece of metal/carbon fibre

Great video very enjoyable explanation of the differences. Made me think of a Jay Leno garage where he mentions on a McLaren I believe they advised he not purchase the carbon ceramic. Mentioning as you did their initial or cold performance. Saying on the street they typically on that car at least have worse performance since they stay overall too cool.
